A non-admin user can view the list of Media assets in Drupal at /admin/content/media, and any DAM assets that appear there show the "Check for update" operation as the first item. Clicking on this takes the user to '/acquia-dam/check-version/{media}', which requires the "Administer media" permission.
This permission would never be given to standard content authors. When a user clicks this option, they get sent to a 403 error. It is confusing and unhelpful.
Create a new module permission to manage access to this screen, or hide this operation from users who do not have the relevant permission to do so.
