Just to amplify: It doesn’t mean they suddenly get credited as writers and get royalties from it 20 YEARS LATER just because they make a MOVIE, and the movie does better than anyone was expecting, and suddenly there might potentially be real money to be made.
That ask is not a great look, whether meant sincerely or in jest, so for her to post about it at all makes her look either desperate and opportunistic, or at best kind of disingenuous, small-time, and (especially for someone who’s turned into more of a producer) kind of surprisingly tone-deaf and naive about the the way artistic collaboration works.
