All apps not showing up in Notifications Section within Settings Menu on iOS 10.3.3

Hi Everyone
I am using an iPhone 7 and i just reset all my settings on my phone .After doing this i have to open each app manually for it to ask me if i want to allow notifications, however some apps don't ask for this option so i have to go into the app settings itself to turn on the notifications.However some apps don't have the settings menu within the app so i can turn on the notifications so i am stuck with not getting notifications for those specific apps.Is there any way to get all my apps to show up in the Notifications section of the settings menu.


Thanks

 

Only selected apps are asking if to allow notifications when i first open them and if they don't ask, only a few have notifications settings within the app.
