How can I use Gemini to find duplicates in Espionage folder?

I'm trying to use the app Gemini to find duplicates in a folder protected by Espionage.
I tried dragging the folder's alias to Gemini, and nothing.
I tried opening /Volumes/EspionageMounts/user/#/folder name with Gemini, and nothing.
I drag the folder to Gemini, start the scan (which goes too fast for scanning over 6,000 items), and it reports there are no duplicates.
Just to be sure it's not a problem with Gemini, I used it to find duplicates elsewhere and then moved a pair of known duplicates into my Espionage folder. So, these are files Gemini just found, but can no longer find once they are in the Espionage folder.
I have the folder unlocked (obviously), and Gemini is on the Espionage whitelist.
Do I have to move everything out of the Espionage folder, clean out duplicates, and then move all 6,000 back?
