you could keep everyone in the same room and use a mixture of selective subscriptions and subscription permissions to create a breakoutroom effect without actually having to switch livekit rooms. If you nevertheless want to keep the different livekit rooms, you could do it via naming.

myRoom

has

myRoom_breakout_0

and the server API lists all rooms that start with

myRoom_breakout_

and send a

come back

message to each one of them.

Sorry, haven't seen your message... I chose the second option, for those reasons : 1. Semantics -> A break*room* is a Room. 2. I think it's simplest than the first solution 3. As server can send message to any rooms (things that I didn't know when I was asking help), I can keep my DataMessage system and reuse some code 🙂 Ty dude !
