Where is the screen use time of vivo true self gtneo2?

Vivo mobile phone hasn't released this one yet. Turn on the healthy use device:

First, in I housekeeper-practical tools-healthy use of equipment-"open right away";

Second, enter the settings-healthy use of equipment-"power on immediately".

Use the function of the device healthily and know the specific time of using the screen every day. There are also functions such as "stop time", "available time" and "application restriction" for children's guardians to set and choose.
