AActorComponent::SetIsReplicated(true)

I dynamically create SkeletalMeshComponent. Will it be enough for replication if you write:

ActorMesh = NewObject<USkeletalMeshComponent>(this);
ActorMesh->SetIsReplicated(true);

I call this from the server side. But SkeletalMeshComponent doesn’t want to replicate on the Client. On the client side he is nullptr. Why? The actor that contains this component is replicated.
