Lock entity not showing in Google home automations

Hi

I have an door entity that is showing up as locked / unlocked in Home Assistent.
Now I want to use this via an Google Home automation to lock / unlock the door

but when I create an automation within Google home, I can not select it in the actions

according to this documentation: integrations - google_assistant: Available domains - Lock

Lock is available

how can I use this entiry?
can I change the entity via an helper to switch (on = lock off = unlocked)?
