After a few trys i made it work.
First i gaved the permission for d2jsp website at Notifications, then i went Security & Privacy Settings and activated "Use Google service for push messaging" , i reloaded the Brave and now d2jsp is registering the Notifications
If you can't make it to work let me know.
I made a test to see if it works :

I believe this may of fixed it(Just waiting on my first push notification).
So weird though as every other site worked without selecting this option.
Much much appreciated TheElderGod
Yes it's strange, but i think the "Google service " = the push notification that works on Chrome aswell
Well i'm glad it works now for you, take care !
