Change Notification Clicked Behaviours

Hi im using one signal to handle my push notification ,im add big picture in my notification , but the big picture is like hidden in the notification, and to shows the big picture i need to hold the android menu and then swipe down the notification, which is hard because we need hold the android menu first without holding the android menu when im swipe down it will expand the android menu instead. So at first im thinking try to make the notification auto expand, but i found some answer in the internet that i cant do that. So my next solution is if its possible, i want when the notification clicked instead open the app, it will expand the notification. Can we do that?
