Animated Map with drilldown

New the forum and relatively new to Logi Info and Studio.  I have a query populating Logi's animated map element of the United States. (Not Google or Leaflet - No Geocodes).  The map populates fine.  I'm looking to drill down into the particular state and have that state's map show up.

I can get both maps to work where an input parameter can change from country view to state view.  However, I cannot get the drilldown to work.  According to the logianalytics article on Animated Maps:

"Drill-down" capability can be added by placing an Action element, as shown above, beneath the Animated Map element. Region-specific data can be accessed using @Chart tokens and passed, as Link Parameters, to the next report or process.

However, I can't figure out what the specific chart elements are for the animated map as this is outside of the chart canvas.  Any ideas or tips?

Thank you,
