I am using the Google Maps JavaScript API to display a map on my website. However, I need to hide the Native American territories that are shown at certain zoom levels. Below is my current configuration:

var mapOptions = { center: new google.maps.LatLng(40.6974881, -73.979681), zoom: 3, minZoom: 3, maxZoom: 16, styles: [{ "elementType": "geometry", "stylers": [{ "color": "#f5f5f5" }] }, { "elementType": "labels.icon", "stylers": [{ "visibility": "off" }] }, { "elementType": "labels.text.fill", "stylers": [{ "color": "#616161" }] }, { "elementType": "labels.text.stroke", "stylers": [{ "color": "#f5f5f5" }] }, { "featureType": "administrative", "elementType": "geometry", "stylers": [{ "visibility": "off" }] }, { "featureType": "administrative.land_parcel", "elementType": "labels.text.fill", "stylers": [{ "color": "#bdbdbd" }] }, { "featureType": "poi", "stylers": [{ "visibility": "off" }] }, { "featureType": "poi", "elementType": "geometry", "stylers": [{ "color": "#eeeeee" }] }, { "featureType": "poi", "elementType": "labels.text.fill", "stylers": [{ "color": "#757575" }] }, { "featureType": "poi.park", "elementType": "geometry", "stylers": [{ "color": "#e5e5e5" }] }, { "featureType": "poi.park", "elementType": "labels.text.fill", "stylers": [{ "color": "#9e9e9e" }] }, { "featureType": "road", "elementType": "geometry", "stylers": [{ "color": "#ffffff" }] }, { "featureType": "road", "elementType": "labels.icon", "stylers": [{ "visibility": "off" }] }, { "featureType": "road.arterial", "elementType": "labels.text.fill", "stylers": [{ "color": "#757575" }] }, { "featureType": "road.highway", "elementType": "geometry", "stylers": [{ "color": "#dadada" }] }, { "featureType": "road.highway", "elementType": "labels.text.fill", "stylers": [{ "color": "#616161" }] }, { "featureType": "road.local", "elementType": "labels.text.fill", "stylers": [{ "color": "#9e9e9e" }] }, { "featureType": "transit", "stylers": [{ "visibility": "off" }] }, { "featureType": "transit.line", "elementType": "geometry", "stylers": [{ "color": "#e5e5e5" }] }, { "featureType": "transit.station", "elementType": "geometry", "stylers": [{ "color": "#eeeeee" }] }, { "featureType": "water", "elementType": "geometry", "stylers": [{ "color": "#c9c9c9" }] }, { "featureType": "water", "elementType": "labels.text.fill", "stylers": [{ "color": "#9e9e9e" }] } ] };

I have tried various styles to hide administrative areas, but nothing seems to work.
