在谷歌火力基地中设置通知时间

Question

有没有办法指定我希望通知出现在屏幕上的时间？或者只是让它直到它关闭。这是代码：

    self.addEventListener('notificationclick', function(event) {
    //console.log('[Service Worker] Notification click Received.');
    var url = event.notification.data.url;
    //console.log('[Service Worker] event url = ' + url );
    //console.log(event);
    event.notification.close();
    // ensure the browser doesn't terminate our service worker before our new window has been displayed.
    event.waitUntil(
        clients.openWindow( url )
    );
});
