Embed and authenticate a grafana dashboard in a web app

I have a Grafana dashboard and I’d like to embed it as an iframe in my web app. Currently, I’m using a jwt-auth to login in my application and, once I’ve logged, I’d like to access grafana without login again. I’ve found a tutorial showing how to something similar using Apache (https://grafana.com/blog/2015/12/07/grafana-authproxy-have-it-your-way/) but I could not apply it to my problem.

I’m new in web development and I’d like something very basic and simple to implement. Is it possible to do what I’m wanting? Some examples or tutorials would be great.
