Only major difference is that I changed the data class to match what's being sent from the backend. Other that that there were a few tweaks I had to make but nothing major

I'll just approved since this has mainly already been reviewed and will probably be fine. One thing that I think is important though is the naming of using Notif instead of Notification. Notification doesn't take much longer to write out and I think it significantly improves readability, so I would appreciate if we can get rid of "Notif".
