JsonSchema Generation doesn't process JObject? like it is stated in the docs

[ghostiek]

Here is the code I ran

using NJsonSchema.NewtonsoftJson.Generation;
using Newtonsoft.Json.Linq;
using NJsonSchema.Generation;
using System;
using Newtonsoft.Json.Serialization;

class Test()
{
    public int Id { get; set; }
    public JObject? Value { get; set; }
}

class Program()
{
    public static void Main(string[] args)
    {
        var settings = new NewtonsoftJsonSchemaGeneratorSettings();

        var generator = new JsonSchemaGenerator(settings);
        var schema = generator.Generate(typeof(Test));

        Console.WriteLine(schema.ToJson());
    }
}

Which generates the following

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "title": "Test",
  "type": "object",
  "additionalProperties": false,
  "properties": {
    "Id": {
      "type": "integer",
      "format": "int32"
    },
    "Value": {
      "oneOf": [
        {},
        {
          "type": "null"
        }
      ]
    }
  }
}

As the docs mention, JObject should be outputting {"type":"object", "additionalProperties": true } instead I got an empty dictionary. Is there a workaround?
