  I wanted to do that, but they don't seem very reliable. See:
  `qDebug() << "ggggg" << flatpakInstallation << g_file_get_path(file) << "." << flatpak_installation_get_id(flatpakInstallation) << "." << flatpak_installation_get_display_name(flatpakInstallation);`
  
    $ plasma-discover --backends flatpak-backend |& grep ggg | sort -u
    discover(3265)/(default) FlatpakResource::installationPath: ggggg 0x7f5170009160 /var/lib/flatpak . default . Default system directory
    discover(3265)/(default) FlatpakResource::installationPath: ggggg 0x7f51700092b0 /home/apol/.local/share/flatpak .  . 
  
  These identifiers don't seem to be very reliable, at least on my system. Using _get_id was actually my first approach.
