Removable devices not available on Steam Deck

[Sarlochin]

When choosing other install locations for the game, the SD card on the Steam Deck is not accessible / viewable.
On other location /run/ there is no folder /media/ where the SD card would normally be.
When you type the location manually i.e. /run/media/[card]/Heroic the path within the Heroic launcher are displayed correctly, however the actual install location remains on /home/deck...
I am not terribly accustomed to an Arch Linux, so there might be something obvious I am missing here.
Maybe someone here has an idea what I am doing wrong.

Flatpaks have limited access by design.
You can install flatseal to add the paths you want heroic to be able to access.
There is a good video on how to use heroic on the deck on the gaming on Linux YouTube channel and another on the Linux experiment channel.

Thank you very much for that fast and helpful reply. Now everything works flawlessly.
