What information was incorrect, unhelpful, or incomplete?

Currently there are 3 way that you can set images to your notification, badge, icon and also image

It's confusing to have so many option to choose from.

What did you expect to see?

I want to have a image schema of where all the bells and whistles goes where in the notification, how it's going to look like on different devices.

A real live demo would be super useful to see and test how it's going to behave.

Do you have any supporting links, references, or citations?

Do you have anything more you want to share?
