madlittlemods (Eric Eastwood) thanks for the fast reply... however there is unexpected (to me) behavior, and i don't know if something's broken, or I just don't understand next steps :(
right now, the current matrix room and gitter rooms aren't bridged anymore
forgive me if this is obvious
but I don't want to migrate the existing matrix community to this new room
All good. As an alternative, we can revert to the old rooms and you could setup your own Telegram bridge in the room which doesn't require admin privileges
