Jitsi authentication via gitlab omnibus or omnibus mattermost user

Hello all,

I did successfully install my jitsi meet app on server and plugin to mattermost.
That’s great!

However I’d like to setup automatic users authentication via mattermost users when they start the meeting instead of creating individual accounts for all my teams.

My installation is based on:
gitlab omnibus with mattermost included: 13.8.4 (9fb9cbf50c3)
jitsi-meet: 2.0.5390-3

Is there anything ready to use or maybe one already went through?

Thanks in advance for all tips and suggestions!
