azure - Authentication error when requesting FHIR resource from Azure FHIR Services

Question

I have deployed Healthcare Workspace and HFIR Service to Azure. I successfully get capability statement and access token.

I'm failing with Get FHIR resource request to get Patient list by Postman. I can see that this request connects to right App registration by correct secret.

I wonder if API permission of App Registration is correct: I have given "Azure Healthcare APIs", which has url https://fhir.azurehealthcareapis.com

However Postmain is requesting: https://healthcareworkspace-my123demo.fhir.azurehealthcareapis.com

I wonder where is problem?

https://docs.microsoft.com/en-us/azure/healthcare-apis/fhir/using-postman

Get: {{fhirurl}}/Patient
