User Profile document locations for snap installation

Nextcloud version (eg, 20.0.7): 20.0.7
Operating system and version (eg, Ubuntu 20.04.2): Ubuntu 20.04.2

The issue you are facing:
Where does NC keep the user profile directories (Photo, Documents, etc.) in Ubuntu 20 snap installation NC 20? I’d like to directly load some of my data directly into those directories, because I have a ton of photos (1 TB) and they could be transferred from an external USB more effectively. Or does this method break the system?
