Streaming .mp4 to Roku

Good afternoon everyone,

Currently, I am having some difficulty getting Home Assistant to stream an externally hosted .mp4 file to my TCL Roku TV. I do not have any issues doing this very thing to a Chromecast and I was under the impression that the Roku TV should operate roughly the same way. Here is the code I’m using to send a video to the Chromecast:

  alias: Video Test
  - service: media_player.play_media
      entity_id: "Entity Name"
      media_content_type: video

Any help anyone would be willing to provide me with would be extremely appreciated as I’d like to get this going as soon as possible. Thanks in advance for the help and support. Have a great rest of the weekend!

Is anyone able to help? It would certainly be appreciated.
