I want to customize serialization based on the type of the property. To do that I would like to read DeclaringType from JsonPropertyInfo. This is an example from Microsoft documentation on how to create such a modifier

    // Custom modifier that increments the value
        // of a specific property on deserialization.
        static void IncrementCounterModifier(JsonTypeInfo typeInfo)
        {
            foreach (JsonPropertyInfo propertyInfo in typeInfo.Properties)
            {
                if (propertyInfo.PropertyType != typeof(int))
                    continue;

The DeclaringType property is not available directly on JsonPropertyInfo though unfortunately (for some strange reason it is defined as internal), but on a generic type that inherits from it. Is there a way without reflection to read it in modifier?
