Expose "Google Assistant" master switch as a regular home assistant entity

Hello all,

I would like to expose the “google assistant” master switch as a regular home assistant entity.

This switch :

Reasoning :

I don’t want people to use Google home if I am not present
(Behind my door, from the balcony with open windows, etc etc).

Having this switch exposed could open a world of automation to activate/deactivate google home based on specific scenarios.
(Or any other way actually… A service that activates/deactivates google assistant works too)

For now, I only found workarounds…
The best one is to plug my google home into a smart plug… and automate the smart plug based on my location… But it defeats the purpose of simplicity that home assistant should bring.

Thx a lot for your feedback.
