Audacious Flatpak: Skins

It's driving me insane. I can't do it. I tried everything I could find online. Can anyone help ?

I tried putting the skin in these places:

/var/lib/flatpak/app/org.atheme.audacious/x86_64/stable/active/files/share/audacious/Skins/

/var/lib/flatpak/app/org.atheme.audacious/x86_64/stable/active/files/share/audacious/Skins/

/home/warmaster/.var/app/org.atheme.audacious/data/Skins/

/home/warmaster/.var/app/org.atheme.audacious/data/Skins/

flatpak override org.atheme.audacious --env=SKINSDIR=~/audacious-skins

flatpak override org.atheme.audacious --env=SKINSDIR=~/audacious-skins

Nothing works
