I have 2 relevant drives. The system drive, and a drive with my game files. The drive with the game files is mounted. However, it is not displayed under “Other devices” and I am unable to select it from /dev/

Installed it using yay from AUR (aur/heroic-games-launcher-bin 2.14.1-1).

Any ideas as to what may be causing this, or how to go about troubleshooting?
