(AuthorizationFailed) Invoking Phi-3 model and getting a response

[devanshithakar12]

Wehn calling workspace_ml_client.online_endpoints.invoke() with the endpoint_name and deployment_name in https://github.com/nicholasdbrady/cookbook/blob/main/examples/phi-3/getting-started-with-phi-3.ipynb, I get an (AuthorizationFailed) error. I tried passing in the api_key as well and setting up RBAC on the resource group.Is there anything else we need to add to this client? Thank you!
