Hi,
The map controller (JS object, an instance of MapField) is stored in the field data-mapController, and I think you can access to that object to perform custom triggers:
var $mapField = $( '.rwmb-map-field' ); // Set specific selector to target the map you want.
var controller = $mapField.data( 'mapController' );
// Then you can run
var map = controller.map;
google.maps.event.addListener( map, 'click', function ( event ) {
controller.marker.setPosition( event.latLng );
controller.updateCoordinate( event.latLng );
} );
