Viewing someone's shared screen in full screen should include a mode to only show the screen and no other elements

Just as going into full screen on a YouTube video covers the entire screen with the video, viewing someone's shared screen in full screen should also include a mode where only the screen is shown, hiding all other elements, thereby taking up the maximum amount of space to view the shared screen.

Having the other elements is nice for seeing who is in the call, but sometimes it's desirable to view the whole screen entirely.
