AnalysisTemplates oauth2 problems with Azure Managed Prometheus

[OlleDecerno]

I am currently trying to get AnalysisRun to query a managed prometheus in Azure but having some issues with the oauth2 authentication. What i've done is creating a analysis run based on the documentation:

...
spec:
    metrics:
    - name: success-rate
      provider:
        prometheus:
          address: https://<workspace>.prometheus.monitor.azure.com
          authentication:
            oauth2:
              clientId: <clientid>
              clientSecret: <clientsecret>
              scope:
              -   https://monitor.azure.com/.default
              tokenUrl: https://login.microsoftonline.com/<tenantid>/oauth2/token
...

but i'm getting 401. I've tried to cURL it manually and got it to work if i add resource="https://monitor.azure.com" but that's not possible to do in the AnalysisRun manifest.

Has anyone got it to work, and if so, how?

Got this resolved by changeing the tokenUrl to use the v2 endpoint instead,

        ...
        tokenUrl: https://login.microsoftonline.com/<tenantid>/oauth2/v2.0/token
