Jitsi has a super easy setup. The only thing you need to know that the room name is the unique ID of the board. It’s mean, if your users join the Jitsi call with the same room name, they will enter same meeting room on the Jitsi platform.
For the Hiro, we are using the first 6 characters of the board code for the room name. Thus, users can join the same room who editing the same board.
