Map Drill-Through

Hello Community, 

I am working on the default map visual. We had a requirement to drill down to that particular site level. Also, when hovering on the bubble, tooltip should pop-up. Right now, we are able to achieve both the option on the map visual. Now the issue is, on default map visual we have to right click and choose the drill through option to navigate one level down. All the users might not know about this right click feature on the map.

Is there any other option to navigate to that site level map from parent level map on a single click? 
If you have any inputs/ sugggestions, could anyone please help me on this?
