Need to add set style feature to Google Layer

[balab2020]

We are trying to use Google Map custom styles feature to style the map. It is possible to have from OL google layer since it create map instance using google api.

How can I make changes and contribute here?

Code snippet on this issue.

OpenLayers.Layer.Google.prototype.setstyle = function () {
              this.type = 'styled';
              var mapStyle = [];
              var styledMapType = new window.google.maps.StyledMapType(mapStyle, { name: "styled" });
              var googleMapObj = mapLayer.mapObject;
              googleMapObj.mapTypes.set('styled', styledMapType);
              googleMapObj.setMapTypeId('styled');
}
