mapping - How to drag a polygon in mapbox-gl-js?

I have a map with multiple polygons. The polygons need to move/update on user click/drag. The functionality I want is the same as this example: https://www.mapbox.com/mapbox-gl-js/example/drag-a-point/

I want to make the polygon draggable like the point example on mousedown, being able to move it on the map, updating the x/y coordinates of the polygon nodes throughout the event, but keeping the geojson size intact throughout the drag.

The point tutorial on Mapbox works well, but I'm unsure how to make it work with polygons.
