In chrome you can make a video fullscreen using requestFullscreen(), but there's a problem: It requires user interaction. Autoplay without mute has the same problem, but it can be solved using --autoplay-policy=no-user-gesture-required. So my question: Is there any chrome flag for fullscreen?

PS: I know about --start-fullscreen, but I don't want the sites to be set to fullscreen when starting the browser.

Thanks in advance!
