[HELP THREAD] how to change the behavior of long pressing the notification?

Hello :) , I have Samsung galaxy S5 16GB rooted and xposed installed, I recently installed CyanogenMod (CM 12.1) and I am missing a feature that existed in my old stock ROM
Which is accessing the app info of any app when long pressing its notificatio, so could you please guys help me if you know how to get this feature again by installing some xposed module or any other app that would change the behavior of long pressing notifications, thanks in advance :)

Notification popups

Hey All,

For the moment, I have stock COK2, 5.1.1 on a N915P (Sprint).

Am I being an idiot, or am I missing a setting? The notifications that should be on the edge screen aren't showing up there. I get a popup at the top of the screen instead.

Under Settings > Edge Screen > Notifications, I have it ticked to show notifications on edge screen, but nada.

I switched to Messenger as default, changed that setting, went back to Signal as my default S/MMS, nope. Can't see anything in Nova Launcher.

The edge screen itself works fine for anything else. What am I missing?

Thanks!
