qubes-video-companion-sender missing dependencies in fedora

[Augsch123]

How to file a helpful issue

Qubes OS release

R4.2 but R4.1 is probably affected as well

Brief summary

qubes-video-companion-sender needs libappindicator-gtk3 and notification-daemon on a fedora app qube. Otherwise there are error messages.

Steps to reproduce

Try to use qubes-video-companion and have a minimal fedora 37 template as the screen-sharing sender.

Expected behavior

Works

Actual behavior

Without libappindicator-gtk3:

(screenshare.py:1126): Gdk-CRITICAL **: 13:58:53.771: gdk_atom_intern: assertion 'atom_name != NULL' failed

(screenshare.py:1126): Gdk-CRITICAL **: 13:58:53.772: gdk_atom_intern: assertion 'atom_name != NULL' failed

Without notification-daemon:
