pfaffman is exploring how to display private messages (PMs) on pages like /unread using findFilteredTopics. They initially tried filtering by query parameters but realized PMs aren’t handled like regular topics. pfaffman discovered that PMs can be accessed using a specific filter format, such as topics/private-messages-group/username/groupName, as seen in the Discourse source code pfaffman. This approach allows retrieving PMs for specific groups, though the exact method for filtering unread or new messages remains unclear.
