Plex Media Player no entity is created?

I’m trying to auto discover my plex server. I see the lines below in my log which seems to indicate that the device was discovered and setup correctly, but I never see a media_player.plex device in my entities.

What’s actually supposed to happen here? It’s wildly unclear from the docs what this component is or how its used. The lack of detail is extremely frustrating. I assume I should get an entity for the plex server, but maybe not? What is this component even supposed to do?
