How to get an interface pointer variable to work w/UPROPERTY()

Ok I found out how to set the TScriptInterface’s interface to another interface. Thank you very much for you assistance! Example for better explanation below:

 Called when the game starts or when spawned
void ALeverActor::BeginPlay()
{
	Super::BeginPlay();

	//Since I'm doing this only in BeginPlay,
	//I'm gonna make a temp variable that gets deleted after BeginPlay is called
	IMyInterface* tempMyInterface = nullptr;

	tempMyInterface = Cast<IMyInterface>(this);

	//Both of these have to be set!
	SelfInterface.SetInterface(tempMyInterface);

	//Since I'm getting the interface in self/this I'm setting the object for this.
	SelfInterface.SetObject(this);

	if (SelfInterface)
	{
		UE_LOG(LogTemp, Warning, TEXT("SelfInterface is valid"));
	}

}
