How to "Lock" a Room?

In my game, after an initial joining phase, I need to make it so new players cannot join. So when a certain event happens in game, I need to be able to “lock” the room and prevent any new players from joining. How can I do this?

Hi @cmaccart9385 , sorry for the late reply. We’ve been having some discussions internally.
This functionality isn’t supported at the moment, but we would like to see how we can add support for it.
Since we’re such a small team we’re always prioritizing and when devs like you bring things up it helps us reshuffle where possible. Thanks for your input!
