Hi!

I wish I could see the duration of the video call as it is in the meet.jit.si test domain, but that it was always visible, not just when the action bar comes out.

I would also like to be able to have a timer, as an example, when a moderator gives you “3 minutes” to speak, that a countdown to 0 would be seen, without any repercussion, only informative.

How could I do it? I have seen some threads where there is said to be a module in prosody, but I don’t know how to enable it.

Thanks in advice.
