Power Automate solution for "Receive calls from this queue" in Teams calling?

We use Teams calling for our intercom (for opening front door) We use a call queue for that with about 15 users/colleagues in it. We use a schedule like person A or B opens the door (are on intercom duty) on monday mornings, person C or D on monday afternoons etc. 

At this moment everyone use the switch button of Receive calls from the call queue on/off manually on the moment they are on intercom duty.

This has a risk that people forget to use this switch at the beginning of their day-part. It is not only a risk, it happens!

I hope there is a Power Automate /Flow solution for this with this functionality, e.g.:

Switch this setting (Receive calls from the call queue) to "ON" every Wednesday morning at 8 AM.

I've tried but I'm a beginner for flows and Power Automate. Simple Flows based on templates are no problem for me, but this one is quite a challenge. 

Can someone help me with this?
