I have launchd and launchctl listed as Full Disk Access. What is DDD?

I have the *.plist files in ~/Library/LaunchAgents. When I try dragging and dropping the files in Files and Folders or Full Disk Access, nothing happens. Is there some other way to set their permissions?

Yes, sorry for the confusion. This is going to be used both internally and deployed in product.

No, I haven't solved the issue.
