Instead of trying to tap the arrow, you should be able press the bubble on one side and drag it out to expand into a detailed notification. The effect would have kind of an elastic response like you're physically pulling it open. Maybe if you pull more than detailed, you could open the app into a pop-up view, then full screan. The more you drag or pull, the bigger and more detailed it becomes until it's a fully opened app.
I know it becomes a pop-up when you pull down. Just like I know when you press and hold the notification, it becomes a split screen. My suggestion is about the effect. Right now, when you pull it down, it just suddenly becomes a pop-up. I'm saying I want it to progress from brief notification to detailed notification to pop-up to full screen as you pull. So the suggestion is not about being able to do something, but about how it's done. The main suggestion is going from brief to detailed notifications, but they could include the pop-up and maybe the split screen. Idk if other customers want that though.
