Google voice search not showing plex results

The main reason I got the android tv with google tv Chromecast was for the easy voice search. However, when I search for a movie that I have in plex, there is no option to open it in plex. I have plex pass premium and have already tried resetting my google tv , and both are in the same network .

The only options I have are "Watch trailer" "Google play" I've tried everything, why the hell is the plex option not showing?
