Load test private endpoints deployed in another Azure region or subscription

Nitin_Joy quick question. In the Azure docs linked here https://learn.microsoft.com/en-us/azure/load-testing/how-to-test-private-endpoint#:~:text=(Optional)%20Check%20Disable%20Public%20IP%20deployment%20if%20you%20don%27t%20want%20to%20deploy%20a%20public%20IP%20address%2C%20load%20balancer%2C%20and%20network%20security%20group%20in%20your%20subnet. it makes reference that an Azure NAT gateway is required if public IP is disabled. I noticed in your blog post you aren't calling out creating a NAT gateway. Would you be able to clarify that even in an Azure Load Test using private connectivity is outbound public internet connectivity required? Or is all traffic contained within Azure's network during the test?
