Problem with share link

Hello, I have a problem with the share link. Some time ago, one of the users generated a link to share the catalog, which was sent to the contractor. Later the nextcloude user account was disabled because it was released. Unfortunately the link has also expired and now I can’t find what exactly he shared. In the database in the _share table, unfortunately, there is no link information anymore. Is there somewhere where I can find what has been shared?

The versions of nextcloud I have are: 15.0.7

Wow, that is an old nextcloud.

Check the activity app.
Ask the user.
