How to embed full Grafana screen(in koisk mode) to web application?

I want to display the full screen of Grafana in kiosk mode on my web application’s screen, not just a panel.

(I’d like to embed THIS Grafana screen into my web application.)

While Grafana supports direct sharing of panels, I’m unsure how to bring over screens that do not support the sharing feature, like the one shown below, into my web application. Simply using the URL to fetch it via an iframe results in a “not authorized” error.

(i tryed iframe code below:

and this is result)

P.S.: My Grafana is set up behind Nginx.

There is a dahsboard panel you could share instead of the browse screen?
