Human-entered closed captions?

Hello and thank you for your work on Jitsi.

I’ve installed Jitsi Meet and Jigasi via the debian packages, and my next step is to get closed captioning working. I primarily need a way for a person to join a call and control captions in real time. Speech-to-text is potentially helpful but definitely not a requirement at this point. Based on my reading it sounds like Jigasi needs to be set up to talk to Jicofo/Prosody as a transcriber but I’m unsure of how a UI would tie into that, or if that is something the Jitsi Meet UI even supports.

I appreciate any and all help you can give, and thanks again.
