Best way to show Grafana in Dashboard?

Finally managed to get this to work. The issue was Node-RED runs on https (IBM Cloud) and Grafana at the time wasn't secured yet (http) which stopped it from loading in Node-RED. Grafana is now secured and the iFrames load.

However I'd like to remove the navigation bar (marked red) from the iFrame but can't seem to find how to switch this off.
