Turn on FireTV with HA Script using notify.alexa_media

Configuration
1

I have some Echo devices and a couple of FireTVs. If I say “Alexa, Announce Hello World”, all the echo devices speak the phrase AND the FireTVs turn themselves on. I would like use this behavior in a HA script, but I’m having a problem.

I’m using the Alexa Media Player integration. I specify the echo device and the fire TV entities in my script, but only the echo speaks the phrase. I expect the FireTV to turn on as it does when responding to voice commands, but it doesn’t. Here’s my syntax, what am I doing wrong? Or maybe FireTV isn’t supported for “announce” in the HA Integration? Thanks in advance for clues or alternative methods to achieve the desired result.

test_bedroom_tv_on:
  sequence:
    - service: notify.alexa_media
      data:
        target:
          - media_player.bedroom_firetv
          - media_player.bedroom_dot
        data:
          type: announce
        message: "Hello World"

OK, I guess this has been discussed elsewhere (sorry about not thoroughly researching before posting). Looks like “Announce” is not supported for FireTV, but “TTS” is. This is apparently an older functionality that uses Alexa’s “Simon Says” skill. I can achieve my objective (turning on the FireTV via script) with the following code:

    - service: notify.alexa_media
      data:
        target: 
          - media_player.bedroom_firetv
        data:
          type: tts
        message: "Hello World"
