×××SPOILERS FOR ENDGAME×××

So regarding to Natasha's death, is it permanent? I know they had to sacrifice something/someone they love in order to get the Soul stone

And I didn't hear Red skulls explanation or Clint's explanation to the avengers about Natasha's death Since the audience in the theater

Were still shocked with her death Since it was so sudden

Now since there is Going to Be a Black Widow movie,

Will she be coming back in future movies before hers?

Or is her death permanent and her movie will be a prequel?
