Grafana OSS web page embedding

Hello everybody,
I’m trying to embedd my OSS Grafana, hosted in a Azure VM, into an external web page.
The authentication is done with Azure AD Oauth2.

The following link (How to embed Grafana dashboards into web applications | Grafana Labs) says that, for security reason, the embedding is not supported for Grafana “Cloud”.

I was wondering if anyone has managed to embed Grafana OSS into a web page successfully.

My issue is that the web page doesn’t pass the Azure Authentication to Grafana.

This is what I have after authentication:

Thanks in advance
