File Browser does not allow loading music folders from Mounted Drives

[antojk]

When I try to "Change Music Folder", the pop up file browser does not allow to load library from disk mount on Gnome Desktop - PopOS 20.04. Refer image below

Due to Flatpak Byte's privacy settings, it can only read the /home folder, But it can be solved.

As expected, the same happens on Debian Buster.
It seems to be another great security feature which tries to protect users from themselves.

Searching around I found this: flathub/org.musicbrainz.Picard#3 describing exactly the same problem I face with Byte. There's a workaround there.

Running flatpak run --filesystem=/media com.github.alainm23.byte works for me.

But it's a strange behavior, mounted drives should work by default.
