BTW something completely different:
We also need to change the logo on the top of the Calls Page and at the bottom in the Jitsi Web and Jitsi Desktop buttons. The used one with colored areas AFAIK is for the Chat / SIP applications. For Meet Jitsi Conference applications AFAIK the pen and ink line drawing is more common.
I discussed that with the Jitsi community / team. Results you see here, user damencho agrees with my thoughts.
