How can I hide Google Maps controls using a code snippet in WordPress?

/**
 * Remove Map Type and Street View controls from Google Maps.
 */
function wpsc_gd_map_params($params, $map_args) {
    $map_type = $params['map_type'];
    $map_canvas = $params['map_canvas'];

    if ($map_canvas == 'gd_map_canvas_directory') {
        $params['mapTypeControl'] = false; // Disable Map Type control
        $params['streetViewControl'] = false; // Disable Street View control
    }

    return $params;
}

add_filter('geodir_map_params', 'wpsc_gd_map_params', 20, 2);.
    return $params;
