How To Deprovision All Devices From Xfinity Stream Application?

Would someone please help me to deprovision and remove all devices from  xfinity stream applications using my account.

 For example: if there is an app on my mobile device, on my smart tv, web browser, etc. and my account is logged into those. I’d like to force sign out of my account on those devices and/or remove those devices so they’d have to login again.

I tried doing this online, through the app, using the xfinity my account app, and calling the support number and couldn’t do it!

I basically would like to sign out everyone automatically from all xfinity streaming applications using my account.

 I’ve read on this forum that only xfinity streaming support team members can do this.

 Please help!

 Thanks in advance.
