By default, a list of current patrons will be displayed at the end of restricted posts. You can choose on which posts categories this list should be displayed in your admin panel > Patrons Tips > Settings > Display patron list in posts with category
This list will only show up if there are currently patrons.
You can also use the Patron list block and shortcode to display a list of patrons where you want.
PRO The list will show patrons who were patrons at the time the post was published. It will only show up if there were patrons during the month when the post was published.
