Obs Ninja + Jitsi meet -?

Have you managed to make OBS Ninja work on your Linux??
I use OBS-Ninja to bring audio and video from my iPhone to my Debian Bullseye Gnome 3.38.4
VirCam form OBS brings Video to Jitsi Meet(only on Firefox not on Chrome nor the Jitsi AppImage)
But I am confused about Audio - how do you bring audio to Jitsi meet from OBS

Any advice or resource are welcome
