Links for internal use

Dear all,

we are using Nextcloud in our organisation with round about 50 persons. Different persons have different access to parent-folders and subfolders. Often documents are written together. These leads to situations where a document stored in:


can be accessed by user1 via

and by user2 via:

Is there any possibility for user1 to give user2 a direct (not public) link to the file? As I understand it, the sharing module only creates public links. I am thinking about an URL with an unique identifier which points to the correct file but only allows access for registrated users who have correct permissions.

Thanks a lot in advance for your help!
