Auth0 to user delegation SAS in Azure AD

I’ve an API registered in Azure using App Registration which has an API permission to user_impersonation (for user delegation SAS access to a storage account)

using the azure endpoints in postman I am able to connect to the API which creates the SAS as expected.

I’d like to be able to authenticate using Auth0 and connect to the API from that route. I followed this guide: Connect Your App to Microsoft Azure Active Directory, it passes the test in the article and am able to get a bearer token in postman but I am getting 401 errors when calling the API[mehndi](
