How to deserialize unknown members with YamlDotNet

Question

This code does not work because

YamlDotNet.Core.YamlException: 'Property 'unknown1' not found.

How do I configure this correctly (if it is possible at all)

using System.Runtime.Serialization;
using YamlDotNet.RepresentationModel;
using YamlDotNet.Serialization;
using YamlDotNet.Serialization.NamingConventions;

var input = @"
Name: John
Count: 34
unknown1:
  xyz: value1
  abc: value2
unknown2: foo
");

var serializer = new SerializerBuilder()
    .WithNamingConvention(PascalCaseNamingConvention.Instance)
    .Build();
var deserializer = new DeserializerBuilder()
    .WithNamingConvention(PascalCaseNamingConvention.Instance)
    .Build();
    

public class Person {

    public string Name { get; set; }
    public string Count { get; set; }

    // this is not a regular property, this is to record all unknown members from the yaml.
    // and when serializing, the content should be serialized again on the same level
    // as Name und Count. 
    public Dictionary<string, string> UnknownProperties { get; set; }
}

If it would work UnknownProperties should contain the following:

{"unknown1", "xyz: value1\nabc: value2"} {"unknown2", "foo"}

alternatively: Dictionary<string, object> UnknownProperties

{"unknown1", {{"xyz","value1"},{"abc", "value2"}}} {"unknown2", "foo"}

The structure of unknown1, unknown2 is not known at this time.
