BrainFrame Client "Select video file" window shows empty for a mounted harddrive

[stephenli2000]

BrainFrame Client "Select video file" window only shows "WDC_SSD" under /mnt. Then if I manually type in HDD, BrainFrame Client will show both. Same thing for every folder and file inside the WDC_SSD,

-rw-rw-r-- 1 stephen stephen 56460949 Oct 9 12:13 /mnt/HDD/data/dilili_videos/dilili_coworkers.mp4

Finally if I type in everything for the dilili_coworders.mp4, it gives me below error,

The "Uploading /mnt/HDD/data/dilili_videos/dilili_coworkers.mp4..." window will stay there forever.

This looks like a snap sandboxing issue. Snap restricts the paths that the program can access.

I think the fix here would be to add the removable-media interface to the Snap. That interface does not auto-connect, meaning that the BrainFrame Client will not get access to stuff under /mnt automatically. However, it would let the user add that permission in the Ubuntu Store or run the following command:

sudo snap connect brainframe-client:removable-media
