Getting input from google home with nodered

Hi guys,
how can i get some kind of input with google assistant/google home in node red? I want to do that:
when someone enter home, my google home ask the user if it have to turn on the light. If the user says yes, the lights turn on.

I’ve successfully set up a scene when i enter home with a hue movement sensor and camera with facebox.I was looking at dialog flow and google action in nodered, but not sure if it’s what i need…
