Can't see other mounted drives

[Alfetta159]

I have a partition on a hard drive that is separate from the drive hosting the OS. How do I set a folder on that mounted drive as my source?

If you installed Byte from Flatpak, this should work:
flatpak override com.github.alainm23.byte --user --filesystem=/path/to/mountpoint

What I decided to do was to just leave my mounted partitions where they were, hide them from the file explorer (I typically use Nautilus or Thunar), and then bind those directories to my Home directory. I really should have done that in the first place.

tl:dr: I use Zorin 18 and Nautilus is really flakey. Others have complained, hence Thunar.
