What is role of speakerstats module in JITSI?

I saw few new modules in Prosody 0.11 where speakerstats is one of them. May I know what functionality is being achieved using this module? Is it available through lib-jitsi-meet as well?

It completes the lib-jitsi-meet one, syncs the info for the newcomers, and you can implement a backend to store it per conference.

Sir is there any documents which talks a little about speakerstats module?

Not really … It is enabled by default in new installations and in meet.jit.si you can see the ui how it works.
Other than the UI, everything is in lib-jitsi-meet and the prosody module jitsi-meet/mod_speakerstats_component.lua at master · jitsi/jitsi-meet · GitHub

When a room is not being used and destroyed the report is fired as event and can be further implemented with custom logic … jitsi-meet/mod_speakerstats_component.lua at 67ac48cac6c292d616729476e2515b8c1dff3711 · jitsi/jitsi-meet · GitHub

Sure sir. Thank you very much.
