How to send whatsapp messages with selenium in an existing WhatsappWeb connection

I tried to send messages to whatsapp with Selenium and C#.
The problem is that, if as an example I am connected to Whatsapp in the current Chrome profile, when the WebDriver is initialized it open a new chrome, without profile and with whatsapp scan QR code.
I want to send messages using the existing browser connection.
I have tried:
var chromeOptions = new ChromeOptions();
chromeOptions.AddExcludedArgument("enable-automation");
chromeOptions.AddAdditionalChromeOption("useAutomationExtension", false);
driver = new ChromeDriver(chromeOptions);
driver.Navigate().GoToUrl("https://web.whatsapp.com/");
And also:
var chromeOptions = new ChromeOptions();
chromeOptions.AddExcludedArgument("enable-automation");
chromeOptions.AddArgument("--user-data-dir=chrome-data");
chromeOptions.AddAdditionalChromeOption("useAutomationExtension", false);
driver = new ChromeDriver(chromeOptions);
driver.Navigate().GoToUrl("https://web.whatsapp.com/");
What I want: to open a new chrome instance, with the existing whatsapp connection,

You need to load the correct profile.
This is the answer provided from uzumaki on how to achieve that:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = webdriver.ChromeOptions()
options.add_argument(r"--user-data-dir=C:\path\to\chrome\user\data") #e.g. C:\Users\You\AppData\Local\Google\Chrome\User Data
options.add_argument(r'--profile-directory=YourProfileDir') #e.g. Profile 3
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', chrome_options=options)
driver.get("https://www.google.co.in")

Changing Default Download Destination for RemoteWebDriver

Im trying to set the default download directory to some thing like:
_webServerFolderDirectory = #"D:\Web\FreshPlatformRegression1\RegressionTestResources";
but i am having no luck finding anything anything to do so. I can find solutions for ChromeDriver (See the line i commented out) but nothing that'll work with DesiredCapabilities for RemoteWebDriver. Here is what the part the calls up the RemoteWebDriver looks like at the moment:
DesiredCapabilities cap = new DesiredCapabilities();
//cap.AddUserProfilePreference("download.default_directory", _webServerFolderDirectory);
cap.SetCapability(CapabilityType.BrowserName, "chrome");
_parallelConfig.Driver = new RemoteWebDriver(new Uri("http://192.168.1.98:4455/wd/hub"), cap);

Incase anyone comes across this issue, I have found a solution. You can use .ToCapabilities() to convert ChromeOptions to capabilities. The code would look similar to this:
String downloadFilepath = #"\\rslfgweb\FreshPlatformRegression1\RegressionTestResources\PDFReports\";
ChromeOptions options = new ChromeOptions();
options.AddUserProfilePreference("download.default_directory", downloadFilepath);
_parallelConfig.Driver = new RemoteWebDriver(new Uri("http://192.168.1.98:4455/wd/hub"), options.ToCapabilities());

C# Mute Audio Selenium Chrome Browser

Like my title says, I am looking for a way to mute any audio on Selenium Chrome Web Driver.
I found this for python(example below) and was wondering if there was something similar for C#?
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--mute-audio")

Try this:
var options = new ChromeOptions();
options.AddArgument("mute-audio");
var driver = new ChromeDriver(options);

How to download PDF using ChromeDriver 2.32 and Chrome in version 57 or higher

Since version 57 Google did remove chrome://plugins option. I found that if I want to download PDF file instead of opening it in Chrome Viewer I need to turn on switch in chrome://settings/content/pdfDocuments
Is there any way to set this option in Chrome driver for example using preferences like below?
private ChromeOptions BuildChromeProfile()
{
var options = new ChromeOptions();
options.AddUserProfilePreference("download.default_directory", DownloadsPath);
options.AddUserProfilePreference("download.prompt_for_download", false);
return options;
}
Or any other way?

options.AddUserProfilePreference("plugins.always_open_pdf_externally", true);
Worked for me.

Chromedriver: How to disable PDF plugin

To mimic functionality of how my Firefox profile is set up, I need to ensure that the PDF viewer for Chrome is disabled. after searching across the internet, the closest answer I find is here
https://code.google.com/p/chromium/issues/detail?id=528436
However attempting any of the suggestions on this page have given me no success
Here is a snippet of code I expect to work
Dictionary<String, Object> plugin = new Dictionary<String, Object>();
plugin.Add("enabled", false );
plugin.Add("name", "Chrome PDF Viewer");
var options = new ChromeOptions();
options.AddUserProfilePreference("plugins.plugins_list", plugin);
driver = new ChromeDriver(options);
Can anyone see what exactly I am doing wrong? this is starting to become a really frustrating issue!

For Chrome 57, I had to use this line instead:
options.AddUserProfilePreference("plugins.always_open_pdf_externally", true);
Additionally, if you ever need to set a plugin yourself you can find it like this:
Navigate to chrome://settings/content (Menu > Settings, Show advanced settings..., Content settings...).
Locate the specific preference (checkboxes only).
Right-click and Inspect the checkbox.
The preference name is the entire 'pref' attribute's value.

I found that this works for Selenium.WebDriver 2.53m, ChromeDriver 2.25.426923, and Chrome v55.0.2883.87 m.
var options = new ChromeOptions();
options.AddUserProfilePreference("plugins.plugins_disabled", new []{"Chrome PDF Viewer"});
driver = new ChromeDriver(options);

This work for me (if the first link is Chrome PDF Viewer )
driver.Navigate().GoToUrl("chrome://plugins/");
Thread.Sleep(4000);
driver.FindElement(By.LinkText("Disable")).Click();
