How to allow flatpaks to access other drives?

[Ant3.141]

Hi, so I have a flatpak (vinegar, to be exact) and I want to use an image that I have stored on another drive. But when I go to that drive (mountpoint), nothing is there. The drive is mounted, I can use it like normal, and any other app can use it, but the flatpak app can’t see it. Since I’m using vinegar, which uses wine, I tried using ‘winecfg’ to add that drive, but it, too, can’t access it since it’s in the flatpak.

So, what do I do to allow them to access other drives?

There may be a way (I don’t know), but the idea of flatpaks was sandboxing them away from access to all your resources (as I recall at least).

KDE:
In KDE system settings, there is the flatpak permission kcm under the security section
Other:
Use AUR package flatseal, to manage flatpak permissions
