Basic user - can the Google home, kick off an automation, via voice?

Our Google Home is on my wifes google account, I can see it in HA and control some functions on it.

I don’t even know much about Google home - but wife ‘found’ our Tuya / Mirabella globes and she can now say to the Google Home “turn the lights off” etc.

I would like us to be able to say “Hey Google it’s night time” and it executes my 3’rd (and final) stage of my bedtime automation lights at home (shut off all house lights, turn on bedroom light, extra dim)

Can this be done?
