I thought about that as well. Main thing is you don't want anyone else to change those things so how can I ensure that? I want a simple user friendly workflow, if that's possible somehow I can add it.
Could just have an admin pin (4 digit) that if entered unhid the entry buttons on client device? Pin could be set when setting up the game
Or you could just do whoever is the first to connect gets the buttons. Most likely that'd be the game admin. So it checks how many connected, if none then assign as admin and show the toggles. If one or more then don't show them. Perhaps?
