Now-a-days touching the screen just takes mute off: touching again stops the video that ought not have started. There are 3 dots permanently above the screen but settings are just basic account, and history/privacy. Playback just quality and speed. Nothing useful for this, unfortunately.
I do have a gmail account, only vecause I was seemingly forced into it years ago when it seemed necessary to reach the Play Store, but I try not to use it as it wasn't desired at the time; and I don't need things involving me linked together in external databases: l believe in privacy. That may be an alternative though, thanks.
