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?
I have raised this question in the #element-web:matrix.org Matrix room. I got an answer: The use case or feature I have described is still being developed and an experimental version is available as a Beta feature.
From when I tested it, the experimental feature shows the amount of people currently connected to the video/voice call/channel, but not who those users are. I assume that will be added in future.
Either way, thanks for the community for clearing that up for us. As soon as this feature is in the official version, I will try getting my friends from Discord to Matrix. In an initial transition phase probably with Discord-Matrix-bridges.
