How to setup OH3 to add "Scene" to google home?

Hi, how to setup OH3, to add custom Scene (and named it for example “Close Window”) to Google home, and then say “ok, google activate Close Window”. And next OH execute custom script/rule.

PS Now in OH i can only use Wall Switches and Sockets (on/off only) i thing with “activate” i can use other type device like Vacuum and remotes.

Add an item as a scene, then have that item activate a rule.
