How could I invoke constructors with parameters in Blueprints? Ufunction seems not working

[anonymous_user_2c841e231 (anonymous_user_2c841e23)]

UCLASS()
class LEARN_API ACustomActor : public AActor
{
GENERATED_BODY()

public:
ACustomActor();
//UFUNCTION(BlueprintCallable)
ACustomActor( FString Name);

I want to use the second constructor in blueprints but it just doesn’t work.
