Custom Notification for Followers & donators

[nemes1sx1st]

Hi ExpertsOnline, I apologize in advance if I am creating a new thread to one that already exists.
I'm trying to add custom gifs to my follower & donator notifications.
These are the gifs I'd like to use and as normal have it say

The format i'd like to use

               GIF
"%name is now following"

Follower Notification:  I would like this to loop & show for 5 seconds

Donation Notification: I would like this to loop and show for 17 seconds

Format I would like

              Gif
%name donated ($ amount)
           message

Thank you very much and if I knew how to do css I would make the effort to do this myself
