Is there an update for FSlateBrush operator?

I’m using version 5.3.2 of Unreal Engine.
UE_DEPRECATED(5.2, “Direct access to Brush is deprecated. Please use the getter or setter.”)
I tried to reset the outlinesetting with getters and setters because of the instructions above.
When I tried to update the FSlateBrush’s OutlineSetting, it didn’t work.

The code inside “Styling/SlateBrush.h” looks like this

	bool operator==( const FSlateBrush& Other ) const 
	{
		return ImageSize == Other.ImageSize
			&& DrawAs == Other.DrawAs
			&& Margin == Other.Margin
			&& TintColor == Other.TintColor
			&& Tiling == Other.Tiling
			&& Mirroring == Other.Mirroring
			&& ResourceObject == Other.ResourceObject
			&& ResourceName == Other.ResourceName
			&& bIsDynamicallyLoaded == Other.bIsDynamicallyLoaded
			&& UVRegion == Other.UVRegion;
	}

The comparison syntax doesn’t include outlinesetting, so it looks like brush didn’t update properly.
Are there any updates like this in Unreal Engine 5.4 or 5.5?
