I have a disk monitoring app that also gives quick access or the ability to eject external drives. Without Full Disk Access, you can’t open a Finder window to the root of the external drive. You can open the parent and select the disk mount point.

I burned a support request on this years ago, and was told that it seemed like a good idea for a future update… a API to open a Finder window at a known path.

macOS used to be one of the most power tool friendly operating systems. Apple Events and AppleScript dictionaries made automation like this so easy. Now everything requires a special permission or specialized Kit to do things that were simple two decades ago.
