How to notify only user that initiated a request using Apple Watch?

I have a number of iOS actions I call from my Apple Watch like “who is home” and “what is the current temperature setting”. Using notify.notify isn’t ideal as it notifies all HA App users. I can see that the ios.action_fired does report the sourceDeviceID but what it returns does not match the service in the notify domain (using node-red). Is there a simple way to notify only the source of the request or do I have to perform my own mapping based on the sourceDeviceID?
