### Feature Request
Are there any plans to include examples of OAuth 2.0 (JWT) authentication using Azure B2C as the OIDC identity provider?

We are facing some challenges in trying to follow this documentation: https://learn.microsoft.com/en-us/azure/event-grid/oauth-json-web-token-authentication

Specifically, for the step with CA certificate including public keys and also with the requirement that the `aud` part of the claim must include the EventGrid namespace since the `aud` part of the B2C token is the application id and doesn't allow for much customization.
