Hi @popimpag,
I’m sorry, but I don’t think there is a simple way to achieve your specific use case, which if I understand correctly, is to make group-associated documents that only the creator and group admin/mods can read or edit. The complication is that because of the way WP_Query works, we have to exclude all of the docs that a user shouldn’t see from Docs queries. So, if a user chooses “only me” for the doc access levels, the doc is given a taxonomy term that prevents everyone else from seeing it. To show the docs you want to include, the query would have to include docs that are group-associated no matter what, but the exclusion takes precedence.
I believe you would have to create a whole new access level, and the logic that protects those docs, so that the exclusion is less iron-clad, which is beyond the scope of a support request.
Best,
-David
