slate and actor code is basic . here is the codes
actor header code :

class UBoxComponent* MyBoxComponent;
UPROPERTY(Category="CustomActors",EditAnywhere,BlueprintReadWrite)
UUserWidget* GetWidgetSample;
TSharedPtr<class SMyCompoundWidget> MySlate;

actor body code:

	void AMyActor::Tick(float DeltaTime)
	{
		Super::Tick(DeltaTime);
		if (GetWidgetSample && MySlate) {
			FVector3d GetActorLocation = this->GetActorLocation();
	
			FVector2d GetPosition;
			if (UGameplayStatics::ProjectWorldToScreen(GetWorld()->GetFirstPlayerController(), GetActorLocation, GetPosition)) {
				GetWidgetSample->SetPositionInViewport(GetPosition);
				MySlate->SetRenderTransform(FSlateRenderTransform(GetPosition));
			}
		}
	}

slate code:

ChildSlot
	
[
	SNew(SBorder)
		.BorderBackgroundColor(FSlateColor(FLinearColor::Red))
		[
			SNew(SVerticalBox)
				+ SVerticalBox::Slot()[
					SNew(STextBlock).Text(FText::FromString(TEXT("From Slate")))
				]
		]

];
