How do I access the list of notifications like a manager on iPhone?

Do you possibly mean Push Notifications, which can be accessed by swiping down from the middle TOP of your iPhone which opens your unread notifications?

Hello!

Which notification list are you looking for? Where do you expect to find it? Which button? Which message are you looking to review?
