Anouncments on a google home device

I am quite new to HA and I can’t seem to figure out how to make an announcement on a google home device. I do have home assistant cloud and do have my account linked but don’t see any obvious way to make anouncments.

What sort of announcement are you looking to have done? I have an automation setup in HA that announces on all my Google Home speakers a reminder each day.

alias: Reminder - Kid's Medicine
description: ""
trigger:
  - platform: time
    at: "18:30:00"
condition: []
action:
  - service: tts.google_translate_say
    data:
      message: Time for the kids medicine!
      cache: true
      entity_id: media_player.all_home_speakers
  - service: notify.notify
    data:
      message: Time for the kids medicine!
      title: Reminder
      data:
        ttl: 0
        priority: high
mode: single

The key item in that automation is the tts.google_translate_say service call.
