Help with launching app in Fire TV via script

I’m trying to recreate a button from the Firemote card example below but on the Universal TV Remote instead. I have added the Fire TV in the example via Android Debug Bridge as I was not able to connect via Android TV Remote as for some reason the IP address of the Host kept failing to connect. But I digress.

When I try to run the script on the left using Android TV Remote commands, I get the following error.
Entity media_player.fire_tv_192_168_0_57 does not support action media_player.play_media.
I believe this kind of makes sense since I wasn’t able to connect the Fire TV via Android TV Remote. But my hope was that since the Firemote card was able to connect to it, then there “should” be a way to connect to it if I can figure out the right YAML…

Any suggestions on how to modify the script below is definitely welcome!

sequence:
  - action: media_player.play_media
    metadata: {}
    data:
      media_content_type: url
      media_content_id: com.retroarch
    target:
      entity_id: media_player.fire_tv_192_168_0_57
