Advice needed (app permissions)

I'm new to the scene. I'm learning to be a software dev but this is my first venture into the MacOs scene. We use Macs in the computer labs at my workplace and I wanted to create a python app that detects if the signed in user is taking up more than 15Gb of the storage on the Mac. The program works great and I've built in some extra functionality so it works with our other management systems but I've run into an issue. The program will need to run on login and if the app runs for the first time it asks them to allow the app to access their data (scan documents folder, desktop folder, pictures folder etc.) and this kind of defeats the purpose of the app as we want to enforce and monitor without the students having the ability to break the program. If the user just clicks no on all of the prompts for permissions the app won't detect storage and I'm back to square one. I've tried adding a info.plist which I though would have fixed the issue but no luck. Any advice on how I can give the program elevated permissions or run something like a sudo instance that ignores or forces the permissions. The logic in my code can be changed too.. no biggy. Just need to find a solution and not spend any money on licenses or API's. Any advice will be greatly appreciated. Alex
