Blocking Unauthorized Access to Copilot

Question

Hello,

I'm working on a project where I need to block unauthorized access to Copilot. By "unauthorized accounts," I mean users who access Copilot through Microsoft 365 E3. The authorized accounts are those with a Copilot license that includes access to the Work/Web options.

How can I achieve this?

Specifically:

How can I block the Copilot application in Teams and the taskbar?

Is there a specific URL or endpoint for Copilot that I can block to restrict access for E3 users while allowing access for those with the Copilot 365 license? i have E5

Thank you for your support.
