Notification sound in an automation on a Android tablet

Hi

How can I make a notification sound / sound when an automation runs, preferably on a specific device?

I have my automations working well to show a pop-up using browser_mod which shows last motion even of a camera, but I want to also play a notification sound on the device.

Home Assistant is running via the Companion App via Fully Kiosk Single App on a Samsung Galaxy Tab A9+

Thanks

Read this project,

Thanks for this.

I have a mp3 (ding.mp3) which I uploaded via Media > my Media > Media Management > Add media.

what is the URL to use to point to this mp3 file in my automation?

Currently use the below but it is hit and miss as to whether I get notification noise on tablet or not, hence wanting to improve it:

alias: test1

  - type: motion
    device_id: 0247f6b9c761444b7d1559fec3da3a9b

      content:

    action: browser_mod.popup
  - action: notify.mobile_app_sm_x210_lounge
    metadata: {}
    data:
      message: Motion detected

So if I use below - what path do I use for media_content_id to access a ding.mp3 I have via Media > my Media > Media Management > Add media

action: media_player.play_media
target:
  device_id: 1710f7496913aefb15083980f380fc8f
data:
  media_content_type: music
  media_content_id: ???????????????
