Replicating Decals

I’m trying to figure out how to replicate decals so that clients can see where bullets are hitting.

So I am doing the following.

UDecalComponent* Decal = UGameplayStatics::SpawnDecalAttached(DefaultDecal.DecalMaterial, FVector(DefaultDecal.DecalSize, DefaultDecal.DecalSize, 1.0f),
    			SurfaceHit.Component.Get(), SurfaceHit.BoneName,
    			SurfaceHit.ImpactPoint, RandomDecalRotation, EAttachLocation::KeepWorldPosition,
    			DefaultDecal.LifeSpan);
    
Decal->SetIsReplicated(true);

However, the decals are still only appearing on the server and not on the client.

I am doing this within an Actor’s PostInitializeComponents

void AFPSImpactEffect::PostInitializeComponents()
{
	Super::PostInitializeComponents();

	UPhysicalMaterial* HitPhysMat = SurfaceHit.PhysMaterial.Get();
	EPhysicalSurface HitSurfaceType = UPhysicalMaterial::DetermineSurfaceType(HitPhysMat);

	// show particles
	UParticleSystem* ImpactFX = GetImpactFX(HitSurfaceType);
	if (ImpactFX)
	{
		UGameplayStatics::SpawnEmitterAtLocation(this, ImpactFX, GetActorLocation(), GetActorRotation());
	}

	// play sound
	USoundCue* ImpactSound = GetImpactSound(HitSurfaceType);
	if (ImpactSound)
	{
		UGameplayStatics::PlaySoundAtLocation(this, ImpactSound, GetActorLocation());
	}

	if (DefaultDecal.DecalMaterial)
	{
		FRotator RandomDecalRotation = SurfaceHit.ImpactNormal.Rotation();
		RandomDecalRotation.Roll = FMath::FRandRange(-180.0f, 180.0f);

		UDecalComponent* Decal = UGameplayStatics::SpawnDecalAttached(DefaultDecal.DecalMaterial, FVector(DefaultDecal.DecalSize, DefaultDecal.DecalSize, 1.0f),
			SurfaceHit.Component.Get(), SurfaceHit.BoneName,
			SurfaceHit.ImpactPoint, RandomDecalRotation, EAttachLocation::KeepWorldPosition,
			DefaultDecal.LifeSpan);

	    Decal->SetIsReplicated(true);
	}
}

And I am creating this AFPSImpactEffect actor on the server via the following.

	if (Impact.GetActor())
	{
		GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Blue, TEXT("You hit ") + Impact.GetActor()->GetName());

		// Deal damage to the actor we hit
		DealDamage(Impact, AimDirection);

		// TODO: move to function
		FTransform const SpawnTransform(Impact.ImpactNormal.Rotation(), Impact.ImpactPoint);
		AFPSImpactEffect* EffectActor = GetWorld()->SpawnActorDeferred<AFPSImpactEffect>(ImpactClass, SpawnTransform);
		if (EffectActor)
		{
			EffectActor->SurfaceHit = Impact;
			UGameplayStatics::FinishSpawningActor(EffectActor, SpawnTransform);
		}
	}

Anyone have any tips or ideas?
