This package hasn’t been updated in nearly six years. I don’t think you should use it.
You do not need to install anything to connect to a Jitsi Meet session. Connect using your web browser.
If you really want a desktop client, then jitsi-meet-desktop would be the maintained option (and the AUR package maintained by xiota of the chaotic-aur).
The jitsi-meet package you were originally trying to install was a component of a Jitsi Meet server, for if you’re trying to self-host.
If you want to self-host your own server, that’s a different story, and requires quite a lot more setup.
