What did the post credits for Wakanda forever mean?

So in the post credits for Black Panther 2 we see Nakia and T'challa's secret child: T'challa. In the comics the Black Panther does not have a child, but in a alternate universe Black Panther has a child with Storm, an X-men. They call him Azari T'challa and he soon enough inherits his mothers storm powers and becomes a part-time member of Next Avengers, a group of superheroes to fill in the main Avengers when they are gone or dead.
