Refreshing embed panels on external website

Hello,

I was looking for a possibility to share a panel from grafana on an external website using the share/embed functionality of grafana, which is regularly updated.

I found that this is somehow possible on the website e.g. of Freifunk (see e.g. this link ) where the embedded panel is regularly updated. However, I did not find out how this is done.

I really appreciate any hints, as I’ve spent already quite some time on trying to get this functionality.

Best regards,
