How to remove the whitelist of oppo mobile phones?

In oppo mobile phone, the white list is a special list, which allows users to add specific contacts or phone numbers to the white list to avoid being intercepted or muted when sending incoming calls or text messages. However, sometimes we may need to unblock in an emergency to receive calls or text messages from others. A whitelist is a list that allows users to make phone calls or send text messages without being intercepted or muted. When we whitelist some contacts or phone numbers, even if the phone is in mute or vibration mode, the incoming calls or text messages of these contacts will ring or vibrate normally. In addition, the white list can also prevent the mobile phone from being maliciously harassed, because only the contacts or phones in the white list can talk normally. First of all, we need to go to the setting interface of oppo mobile phone, find the "sound and vibration" option, and click enter. Then in the "Sound and Vibration" interface, find the "Do Not Disturb" option and click Enter. Finally, in the "Do Not Disturb" interface, find the "Allow Disturbance" option and click "Close" to cancel the whitelist.
