Grafana iframe display within KIP

[pjsf1000]

Hi
Like a few folk during lockdown I have been having great fun installing and configuring openplotter/signalk/kip/grafana/InfluxDB etc 

This is my first post to this site and I would be grateful for your help.

My setup.  OpenPlotter on RaspPi4.  Added InfluxDB/Grafana and successfully displaying graphs in Grafana and custom information in KIP. 
I would like to be able to display a grafana panel in KIP.   I believe I have configured grafana to permit embedding  
I have changed the grafana ini to 

allow_embedding = true
cookie_samesite = none

• From Grafana panel I obtained the below URL
  

<iframe src="http://openplotter.local:3001/d-solo/RVSdfcggk/engine-and-weather-graphs?orgId=1&refresh=30s&from=1615817861678&to=1615818761678&panelId=12" width="450" height="200" frameborder="0"></iframe>

• When I copy this URL into the KIP 'embed web component' and lock display I get the following displayed:
  Cannot GET /@mxtommy/kip/%3Ciframe%20src=%22http://openplotter.local:3001/d-solo/RVSdfcggk/engine-and-weather-graphs

• If I copy the URL portion I obtained from Grafana into a browser window i see the correct grafana panel I want. 
  

http://openplotter.local:3001/d-solo/RVS...panelId=12" width="450" height="200" frameborder="0"

Would appreciate any suggestions, 

Many thanks!!
