Specifying audio sink in openhab rules

Hello,

Having some issues setting up notification sounds for when a door is opened. I have 7 google home mini throughout the house and would like only select ones to play depending on what door is opened.

The rule (see below) is working fine however only plays to default sink. How do I specify what sink I would like the rule to play over?

rule "backopen"

when
        Item BackDoorStatus_DoorWindowStatus changed to OPEN

then
        sendBroadcastNotification("The Back door has been opened!!")
	playSound("doorbell.mp3")
        
end

Look into the Audio documentation . Under Actions you will find all overloads for playSound. The last starts with the Audio Sink!

Thanks!
