Under SpecFlow/Selenium, I'm starting Chrome like this:
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);
Can it be done with headless? I also tried --incognito and incognito as well as placing the flag at different indices within the AddArguments() call.
