HTPC from Flatpak: 1.66.1.215-6343cfaf
The app doesn’t associate properly with the window manager, and so does not have its icon in the task switcher or Overview-type effects:
Checking KWin debug console, the desktopFileName is empty and the resourceClass is set to Plex HTPC.
This is probably because the application needs to call setDesktopFileName, eg QGuiApplication::setDesktopFileName("tv.plex.PlexHTPC").
