How do you select crew members for a gta v heist?

The only verified source is a Wikipedia overview of Grand Theft Auto V, which describes the game's setting, protagonists, and general gameplay mechanics. It mentions that the story follows three protagonists who attempt to commit heists, but it does not provide details on how crew members are chosen or the criteria used in the game for selecting them. Without additional documentation or official guides, it is not possible to explain the selection process for heist crews in GTA V.
