Google home and arm alarm

I setup Google home with Nabu Casa. It’s working and shows scenes and switches I expose.

I want to arm the alarm at night with Google home. I could make an automation, trigger off a scene, and then just trigger the scene? Is there a way for Google home to do alarm stuff? I could also make a virtual button that arms the alarm?

I already have an automation that if alarmed armed, do all the things I want, would like to reuse that if possible.

I created a script called “house alarm” to arm the alarm and then just ask Google to “activate the house alarm”. It works perfectly
