Shared read-only files are not redeployed

Hi Community

I have shared files that are read-only. The user deletes these files, but they will not be re-provisioned. How can I change that the files are displayed again to the user?

There was somehow the discussion to put a section where the user can see all the shares he rejected (and add them again).
If you are on a folder level for sharing, the groupfolder-app is supposed to be undeletable by users.
