Flatpak support?

[JanSvobodaJenik]

I have Spotify installed as a Flatpak and I'm getting this error:

62914564
Traceback (most recent call last):
  File "<path>/SpotifyTray-master/./spotify-tray.py", line 143, in <module>
    main()
  File "<path>/SpotifyTray-master/./spotify-tray.py", line 137, in main
    spotify = SpotifyWrapper(spotify_id, spotify_process)
                                         ^^^^^^^^^^^^^^^
UnboundLocalError: cannot access local variable 'spotify_process' where it is not associated with a value
Segmentation fault (core dumped)

Specs:

Distro: Fedora Linux 40
Desktop Environment: KDE Plasma 6
Graphics Platform: Wayland

Is this related to Spotify being Flatpak? If so, will the Flatpak version ever be supported?
