The client cannot own a vehicle

What I want to do is that several clients can enter and drive the vehicles, but the only one that can is the SERVER
Vehicle Blueprint

NOTE: The Possess to Client is in RUN ON SERVER

Third Person Character

You need to set the proper Player Controller who own the pawn you want to take the controle of the car.
Here you set only the 0, who from the point of view of the server is the first player who join the session.

Here I have tried to save it using get controller but I have not been able to do it, could you guide me?
