How to set notifications as "implicit push" on iPhone?

In iOS 12 and later systems, if you only want to view the notification messages of an App through the notification center, but don't want them to appear on the lock screen, and you don't need to play sound, display banners or mark icons, you can turn on the implicit push function:

1. Open the notification center, and slide a reminder or a group of reminders to the left, ignoring management;

2. Here, you can turn on implicit push. When turned on, all notifications of this application or group will not be displayed on the lock screen, nor will they play sounds, light up the screen or display banners. Only notifications can be viewed in the notification center.

If you want to see and hear these notifications again, push the notifications to the left in the notification center, tap Manage, and then tap Explicit Push.

In addition, if you click Close in the above interface, all notifications of the App will be closed. To turn on the notification function of an application again, go to Settings-Notifications, select the corresponding application, and then click Allow Notification. You can also click "Settings" here to change the reminder style or reminder settings for a specific application.
