Adjust modern Manage access panel for better overview
When assigning permissions directly to document library, the sorting of the user list in Manage Access panel is confusing. First the sitecollection admins are displayed, which is hidden in classic view. The business owner of the site usually doesn´t know this person (technical admin), lose confidence in system and is trying to remove it from list. When switching to classic view via "Advanced" the user is not displayed in the list.
Please adjust the listing in modern "Manage access" according to classic approach.
