Teams Survivable Branch Appliance firewall ports to Microsoft 365

Looking for information on the specific MSFT 365 ranges that a Teams Survivable Branch Appliance requires access to.

The planning guide, Direct Routing SBA - Microsoft Teams | Microsoft Docs, details that tcp/443 is used by Microsoft SBA Server to communicate with Microsoft 365 and should be allowed on the firewall.

Customer does not allow unfiltered access to the internet from the server on tcp/443 - can anyone help with the specific service tags that a Teams SBA requires access to ?
