Can players join other players story missions in gta online?

Grand Theft Auto Online is an online multiplayer action‑adventure that allows up to thirty players to explore an open world based on Southern California. The Wikipedia entry describes the game’s multiplayer nature and the ability to participate in cooperative or competitive modes, but it does not mention the existence of story missions that players can join. Because the evidence does not address whether a player can hop into another player’s story‑mission experience, we cannot confirm that such a feature exists. If you are looking for ways to join missions with friends, the game does provide various cooperative missions and heists, but those are not identified in the source as “story missions.”
