Hello, I'm using pulumi with C# and I'm trying to create azure front door that would load balance two aks clusters in different regions, the hostname property under azure front door that is in the below endpoint, if I put a hostname then pulumi or azure complains as it requires cname registered and it doesn't accept any randomsite.fd.net subdomain, and if I removed the hostname to make azure relay on auto created sub domain, I get an error saying hostname is mandatory, what am I missing here FrontendEndpoint = new[] { new Azure.FrontDoor.Inputs.FrontdoorFrontendEndpointArgs { Name = "exampleFrontendEndpoint1", HostName = "example-FrontDoor.azurefd.net", }, },
