On the issue linked above, there is a link to this comment regarding voice rooms. There it states that the following functionalities among others are/were planned:
Show participants, even when you’re not connected
Disconnect when leaving the room
For me, this implies exactly the use case I’ve been looking for. But that was back in 2022. I assume this is still planned to be implemented, just has a lower priority, but I could not find a statement regarding my assumption. Any ideas?
