Starting Jitsi desktop client

I’m trying the “Jitsi Desktop stable build line” with repository for Debian (10), and, on first application launch, it shows a splash box with only “NimbuzzAvatars” message under an empty progress bar.

No progress and no visible change.

Is this a desktop client for Jitsi Meet services?

No, this is a different application with different purpose.

You don’t need an application just open chromium and start your meeting.
