How to add multiple actors to ignore while Linetracing

[SHuRiKeN]

FCollisionQueryParams TraceParams(FName(TEXT("")), false, GetOwner());
GetWorld()->LineTraceSingleByObjectType(OUT ActorHit, PlayerViewPointLocation, LineTraceEnd,
FCollisionObjectQueryParams(ECollisionChannel::ECC_PhysicsBody), TraceParams
);

if (ActorHit.GetActor())
{
	UE_LOG(LogTemp, Warning, TEXT("Actor that I am hitting is %s"), *ActorHit.GetActor()->GetName());
}

}

How can I add multiple actors to ignore list like we are ignoring GetOwner() here.
Is there a better way to do this working with multiple actors eg: have a certain type of tower in my game attack a certain type of Actor/Hero only. So I can create booleans or Actor Array but what should I do exactly

Use one of the functions on FCollisionQueryParams

FCollisionQueryParams::AddIgnoredActor

FCollisionQueryParams::AddIgnoredActors

Thanks it worked… Also if my linetracing does not start from the Actor how can we remove GetOwner() from

FCollisionQueryParams TraceParams(FName(TEXT("")), false, GetOwner());

as we have to pass in some actor… Can we simply say AActor here and leave it…

Update : Oh I think we can use different constructor given here https://docs.unrealengine.com/en-US/API/Runtime/Engine/FCollisionQueryParams/index.html
