API call to disconnect MS Teams Connection for users

I setup an API in ringcentral dev that I’m using in a Microsoft Azure Automation runbook to execute an offboarding for a user I specify.  The first step we must complete is toggling the switch off for the MS Teams connection on the user I’ve specified in my automation.  How would I set this up?   I’m using powershell 7.2 for my API call. 

I’ve got my powershell script executing properly and disabling the user account, but it will not allow me to disconnect MS Teams connection which is what I need done first.
