File-drop (upload-only) for Nextcloud users (local/federation)?

A stupid question. Sorry.
For anoymous upload i can configure File-drop (upload-only) and use it.


How can i implement it for registered users?

User “test” logged in and uses the share “Drop”:


I do not want that the user “test” can see the uploaded files from other users.
Or must i write an issue?
