I would like to know how could I set my collision box component size in c++, I tried using SetBoxExtent and InitBoxExtent, but it is not working. What should I do?

UBoxComponent* BoxCollissionComponent = CreateDefaultSubobject<UBoxComponent>(TEXT("BoxCollision"));
    	BoxCollissionComponent->SetCollisionProfileName(TEXT("Collision"));
