Partecipants Count in room

Hi, I see that on your site (https://meet.jit.si/) there is a counter of partecipant. I have installed jitsi-meet on my server but i do not have partecipant counter icon. Could you help me??

Which version did you install, latest from stable or from my unstable?

The latest stable version

I suspect that is still not there, you need to install unstable.
