New Jitsi Meet Electron app 2.0.0 - start issues on Debian 10 with workaround

Dear All,
just download & run the very recently updated jitsi-meet-electron version (2.0.0) in Debian 10 (sid), however failing:

Running AppImage without root:

[77755:0408/] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I’m aborting now. You need to make sure that /tmp/.mount_jitsi-F5jV3G/chrome-sandbox is owned by root and has mode 4755.
Trace/breakpoint trap

Running AppImage with root
[77794:0408/] Running as root without --no-sandbox is not supported. See

sudo sysctl kernel.unprivileged_userns_clone=1
