How can I access FindLookAtRotation directly?

I’m trying to have an object always be looking at the players position like so…

for (int i = 0; i < m_nTrickshotObjects; i++)
	{
		const FVector PlayerPos = GetWorld()->GetFirstPlayerController()->GetCharacter()->GetActorLocation();
		FRotator Forward = UKismetMathLibrary::FindLookAtRotation(ObjectLockIcons[i]->GetActorLocation(), PlayerPos);
		
		ObjectLockIcons[i]->SetActorRotation(Forward);
	}

Yet when I compile I get an unresolved external symbol error. I read that UKismetMathLibrary is not meant for general C++ use so how can I access FindLookAtRotation directly?

The answer was to access it through FRotationMatrix::MakeFromX which is called within FindLookAtRotation using the target location minus the object location like so…

for (int i = 0; i < m_nTrickshotObjects; i++)
	{
		const FVector PlayerPos = GetWorld()->GetFirstPlayerController()->GetCharacter()->GetActorLocation();
		
		FVector Forward = (PlayerPos - ObjectLockIcons[0]->GetActorLocation());
		FRotator PlayerRot = FRotationMatrix::MakeFromX(Forward).Rotator();

		ObjectLockIcons[i]->SetActorRotation(PlayerRot);
	}
