Virtual devices and Google Home

I’m trying to make a switch in Homey to start music from Spotify on one of my Google Minis. I made and virtual Kettle button from the Device Capability app, and put this into an automation in Google Home that should start music on the speaker. But when i push the button in Homey or Google Home app, nothing happens.

The automation works if I manually start it in Google Home app, and the state of the button changes if I press it in Homey or the Google Home app (on/off).

Anyone know what can be the problem here?
Also: Is it possible to make i push button and not and on/off button?
