Sync map with slicer fields

Hello everyone,

I would like to have a map to work as a slicer, kind of like a two stages slicer.

Let me explain I have information regarding the implementation of projects in 3 countries. What I want to do is use a map to filter projects in a slicer, that means the map filter the fields shown in a slicer. Then with the filtered list in the slicer select a project to see the results in a chart.

I attach an example of what I want

In this example, ideally  if I select Guatemala then the slicer only shows project Number 1, but if I select Honduras then the slicer should show projects Number 1 and Number 4.

I hope the example helps to make it clear.
