Can someone say how can I get to this network management window in my android device My device is vivo 1718 android 8.1. I have found this Network Management window when I didn't turn on mobile data access for one app. That app pops up an alert to change the network access and when I press to change it, I am directed to this window:

But after that I can't find it anywhere in my settings.
As in @dewey's comment that is located inside iManager App 'Network management' section. Here is the path.

iManager -> Data Monitor -> Network Management
