How do I integrate an existing media streaming platform into my plex? For example, the Chosen tv show has its own streaming app for mobile devices or can be streamed thru a browser at The Chosen TV Series | See the Videos & The Trailers with the Free Chosen App Today!… In addition, the show is available to stream from Amazon Prime as well as some others.

So the question is, what platorms can be integrated into my Plex so I can stream content from there and watch it in Plex?

Other platforms cannot be integrated into Plex. It is not possible to route the video data of other streaming services into Plex.

All Plex can do is to notify you that an item is available at another streaming service (or a personal Plex server). If you select Amazon Prime as one of your preferred streaming services, Plex should show you the availability on Amazon prime in the Plex app.
