Hey, is there a way to assign a system assigned identity to a SignalR service?

This a weird one, Pulumi Inc says they nightly build off the ARM API. Well ARM, bicep, and that nasty Terraform all show an identity section on the officials documentation. https://docs.microsoft.com/en-us/azure/templates/microsoft.signalrservice/signalr?pivots=deployment-language-bicep https://docs.microsoft.com/en-us/azure/azure-signalr/howto-use-managed-identity#use-a-managed-identity-in-serverless-scenarios
