Unable to find or open media folder in MX-Linux (flavor of Debian)

[bitshifter52]

Describe the bug
I installed LightZone using flatpaks in the MX Package installer application. LightZone starts but cannot find the system media folder. This is part of the OS and looks like: /media/$USER/LPhoto/. LightZone will not open symlinks to any drive or folder. LightZone opens the Pictures folder but tries to open the symlink as a file.

To Reproduce
Steps to reproduce the behavior:

1. Open LightZone
2. Open
3. Cannot scroll to appropriate folder
4. Folder not found (or with symlink it tries to open that as a photo)

Expected behavior
Open and edit images.

Additional context
TLDR: Unable to locate or open the system Media folder. Also unable to access symbolic links (symlink).

Did you set a permission to access the /media/ directory with flatpak?
cf. https://askubuntu.com/questions/1086529/how-to-give-a-flatpak-app-access-to-a-directory

On my environment (Ubuntu on WSL2), the /media/ directory was not shown first time, but it appeared after setting the permission. I haven't checked if symlinks work yet. Symlinks work on my environment, too.
