[1] Does it run from a browser or do you have to use thje desktop editors to use it?
[2] I beleive it can host jitsi calls? Are these calls SELF hosted (private) in a FOSS deployment ,or, are these calls directed via the corporate jitsi site?
Jitsi plugin v1.0.0 can start a new conversation without need to run self-hosted instance by entering room name in respective field in the plugin and then pressing Start to launch plugin;
It can also use your own self-hosted instance - for that you need to define address of your self-hosted Jitsi in Domain field, provide a name for your room and press Start to launch plugin with your self-hosted Jitsi.
To run the plugin in browser you will be prompted to grant access to devices’ microphone and camera.
I see that you are running Workspace already, I’d recommend running DocSpace separately them to avoid conflicts.
If you face any issues with DocSpace installation, please start a new topic or try looking for existing ones. This topic is about Jitsi and I do believe your questions were answered. Closing this topic as solved. Feel free to contact me via PM if I’m wrong.
