Change entities - imported switch to password protected voice activated door


A potentially easy problem, but i reallt can’t figure out the solution…

My integrations:

From IHC integration i’m importing a switch. If that switch is activated (on/off shortly) my garage door opens.

I would like to activate the imported switch via Google assistant, BUT before GA activates the switch is has to require a password (fx. 4 digits) - Doing the same thing again closes the garagedoor. There is no sensor or anything present.

I’ve tried several thing like “locks” etc. but it won’t work.
Any good suggestions?
