I’m trying to extract GeoJSON boundary polygons from Google Maps for localities. In Google Maps, there’s a distinctive dotted line boundary visible when searching for a place name (see image attached).

I’ve attempted to use OpenStreetMap for this, but it doesn’t include all the polygonal boundaries I need.

Is there a Google Maps API or another method to programmatically retrieve these boundary polygons? My goal is to dynamically display these boundaries in a mapping application based on user inputs.
