Coordinate map click actions on graphed points

Hi folks, I'm using ELK stack 5.6.
I have a working coordinate map visualization using iptables logs for data.

I seem to recall when I ran ELK on 1.x or 2.x that you could drill down in a dashboard when clicking a coodinate point in the map itself.

Hovering over a coordinate point shows the count and coordinates, and turns the cursor into what looks like a clickable link, however nothing happens when its clicked. While I'm sure this is some javascript functionality, this is beyond my understanding.
I see the same behaviour in Chrome and Firefox.

Can anyone shed some light on this?

Thanks
