How do i access my games files that i get from flathub?

i m trying to access my stepmania files to add new songs but i dont know how

the app itself will be in ~/.var/app but that’s not necessarily where your app will expect the songs

@apex319 take a look inside ~/.var/app/com.stepmania.StepMania/.stepmania-5.1, maybe one of that folders is what are you looking for.
