Mednaffee (Flatpak) not seeing all drives

[ZeddieXX]

I have another internal SSD drive I have all my ROMs but Mednaffe isn't showing it in the file picker.

I'm on Fedora 39 and Mednaffee was downloaded from the Software store app.

I think it may be a permissions issue, but unsure how to fix it (not a Linux/Flatpak expert).

Download Flatseal from Flathub, go to Mednaffe > Filesystem and add the /mnt path in Other files.

Since flatpaks are running in a sandbox, they cannot see anything outside the Home folder by default, unless you give them access to other folders.
