How to Access Stored Feed Messages Not Visible on the Community Site in Tightknit Studio

Hey team, if a feed has been storing messages but isn't accessible via the Community Site, how do we see those past messages? ex. for my internal teammate, using the Tightknit Studio. I asked AI in the documentation and it recommended filtering by channel in Studio -> Discussions, but there's no "filter by feed" there. Is the storage more for analytics, and not for actual browsing/engagement, unless it's on the Community Site?
