How to rename a discovered media_player?

I have a roku3 box that is being automatically discovered, but is coming up with an entity as media_player.roku_632643060083. I want this entity to be renamed to something more easily readable. I looked at the roku page and there wasn’t really all that much there. Not sure what to add to my configuration.yaml to get this named differently since it doesn’t show up in any other file or the configuration.yaml itself.

Customizing entities.
