Cloudflare Zero Trust Egress IP List

Hello,
I am planning to block my employees’ access to GitHub Enterprises via IP Allowlist. All my employees are required to use a zero trust network to access all university technology resources. I’m already allow listed IP Address of our campus network to GitHub Enterprises and it go very well.

The question is:
Is there a list of IP address ranges (ipv4/ipv6) that I can use to do ip allow list? Currently, I and the DPTSI team do not plan to use the dedicated egress IP Zero Trust service.
