No notification with lock screen screen and no sound

I have an automation that send me a notification with a screenshot of my entrance camera every time someone ring the door.
Is it possible to add a sound to it? Also the notification remain hidden behind the lock screen and I can see it only after unlocking the screen as an icons in the status bar.
Thank you
Andrea

Custom sounds are not available yet however you can modify the existing notification channel. Make sure to send the notification with ttl: 0 and priority: high so it wakes up the device and shows up on the lock screen.

See the android example here: https://companion.home-assistant.io/docs/notifications/critical-notifications

This is useful for me too, don’t suppose you know how to translate the extra parameters into the JSON node red uses?

Edit to add current JSON:

{
    "message": "Staging notification",
    "data": {
        "ttl": "0",
        "priority": "high"
    }
}
