How to block the message reminder of nailing?

Many enterprises will use nailing software at work. Can that nail block the single chat, group chat and nail phone calls initiated by non-colleagues and non-friends? Here's how to refuse other people's news.

How to refuse others' news? 1, open the phone nail, and click Settings in My Options at the far right of the bottom.

2. Click to enter the privacy option.

3. Turn on the switch to the right of shielding unknown contact information.

I want to remind you that you are all colleagues in the same enterprise structure. In order not to affect the communication between colleagues, it is definitely not supported to block colleagues from sending messages to each other for the time being.
