How to set conversation response to just "ding" sound in automation?

Configuration
1

HA has the nice ding sound when you use sentence local command like “Turn on the lights” and the lights are in the same room as the voice assistant. I would very much like to trigger this as a conversation response from my automation. Is this possible?

I have checked Method of disabling conversation response in an automation - #7 by mchk and Completely disable conversation response from custom sentence automation? - #4 by adynis

But this is a bit different. I dont want “no response” basically I want a “custom audio response”. It would be cool to use what already is available in HA, like the sound before announcement is broadcasted, or whatever else is bundled.

I think this would have to be added as new action “Set response audio”, but maybe I am wrong and it is somehow possible?

Thanks!

  - action: media_player.play_media
    metadata: {}
    data:
      media:
        media_content_id: media-source://media_source/local/acknowledge.mp3
        media_content_type: audio/mpeg
    target:
      device_id: "{{ trigger.device_id }}"
  - set_conversation_response: ""

the sound is here, place it in your media folder
