I would like to Implement X-CSRF pattern as per the documentation below:

https://web.archive.org/web/20230325015450/https://learn.microsoft.com/en-us/azure/api-management/policies/get-x-csrf-token-from-sap-gateway

https://github.com/Azure/api-management-policy-snippets/blob/master/examples/Get%20X-CSRF%20token%20from%20SAP%20gateway%20using%20send%20request.policy.xml

But the above documentation is for SAP Gateway. Is there any documentation where the Gateway is Azure API-Management gateway itself?
