Plex media guide on Amazon fire TV

Hi,

I have recently purchased Roomie and so far I love it and have quite a few devices setup (albeit being a complete novice).

I was wondering if it was possible to have my Plex guide from PMS to show on the Amazon fire TV activity. It currently shows on my PHT activity (PHT and PMS run on the same server) but would be good to have this on the Amazon Fire TV too as I have plex installed on there too.

Many thanks,

Daryl
