Wakeup screen for notifications

[KanRom]

Hello world

I'm wondering where I can find the option to wake up the screen when I receive a notification because I turned it off a while ago but I don't know how to turn it on again because I can't find it for some reason

Under settings/notifications/app notification

And then?
I need the screen to wake not help with getting notification
