How to play Jellyfin movies on Nvidia Shield via Home Assistant Voice?

I recently bought Home Assistant Voice Preview Edition, I installed Home Assistant and configured Jellyfin and Android Tv Remote (Nvidia Shield Pro) integrations.

I can use voice commands to turn on/off Shield.

I would like to use voice commands to :

  1. open Jellyfin app on Shield
  2. play a movie of choice by name

Is it doable these days ?
