plexmediaplayer won't find mediaserver

[trappedinspacetime]

First of all, thank you for your work.

I added your repo and installed plexmediaplayer

   flatpak --user remote-add tingping https://dl.tingping.se/flatpak/tingping.flatpakrepo

   flatpak --user install  tingping tv.plex.PlexMediaPlayer

When I launch it, it looks for plexmediaserver but can not find plexmediaserver
