title: Start headless chrome in incognito
body: <p>Under SpecFlow/Selenium, I'm starting Chrome like this:</p>
  
  <pre><code>    var options = new ChromeOptions();
      options.AddArguments("--headless", "--window-size=1920,1080", "--disable-gpu", "--disable-extensions", "--no-sandbox", "-incognito");
  
      var svc = ChromeDriverService.CreateDefaultService();
      svc.Start();
  
      Context.Driver = new ChromeDriver(svc, options);
  </code></pre>
  
  <p>As the <code>-incognito</code> flag on the Chrome executable starts the browser in incognito mode I was thinking this was do the same for headless mode. I was wrong. Can it be done with headless? If so, how?</p>
  
  <p>I have also tried <code>--incognito</code> and <code>incognito</code> as well as placing the flag at different indices within the <code>AddArguments()</code> call.</p>
