You would need to find a different way to get these notifications to Hubitat, this integration will not provide these events unfortunately at this time although that could change the future if someone figures out how to get the events from the API.
I use IFTTT currently to do this which will turn on a virtual switch:
Virtual switch in Hubitat:
It's setup to automatically turn off after 5 seconds but you can modify that to your liking. I have another one setup for motion just like I do for sound as shown above.
As I mentioned, Tasker is another option but never really tried it before. There could be other ways to do it from Alexa or Google Home using a Virtual device instead of IFTTT, some people don't like to use IFTTT since it's slower for some people although for me just using it for this purpose it seems to be pretty close to instant even with the free version of IFTTT.
