<p>This plugin restricts access for Authors and Contributors so they can only see their own Media Library uploads.</p>
<p>This has two main uses: Make it easier for Authors to locate their own uploads when Media Libraries grow very big and prevent Authors from using or downloading media that belongs to other users.</p>
<p>Admins and Editors will still be able to see everyone’s uploads.</p>


Restrict Media Library Access

Muy útil

This plugin works fine in WP 5.7.1 

It's just the example code from the official WP docs for the ajax_query_attachments_args filter, with a line added to check if the current user is an administrator. It's very simple.

There's no reason this plugin shouldn't work in an up-to-date WP installation
