我的应用程序目前从Firebase控制台接收文本、图像和混合推送通知。我希望也能够通过Firebase控制台向应用程序用户发送URL通知。当用户点击该通知时，将会被重定向至特定的URL，例如 www.facebook.com。如何在以下代码中实现这一功能？

// here in onMessageReceived whether the app is in the foreground or background. Data messages are the type

// When the user taps on the notification they are returned to the app. Messages containing both notification
// and data payloads are treated as notification messages. The Firebase console always sends notification
