Feature request - channel permission games

So i was just thinking about this feature and i had the same idea about a year ago, i think it could have faults but ill suggest anyway, what harm can it do. So if you can make a channel that with the right permissions only allows people in it who are currently playing a game, that game being whatever the permission will allow. For example: If im in a CSGO channel on my discord and people join and talk and then i have to move them but i dont always like being in admin only channels because sometimes people cant join etc. So if me and my friend are playing Battlefield 5 and we dont want people interrupting us Unless they want to join us on bf5 they can join the channel only when the game is open and discord can already detect that, maybe they cant talk or they get kicked when the game isnt open but they have joined the channel before which avoids people being able to launch said game, join channel and then close the game.
