How to read XML RabbitMQ messages from third-party systems

[Cododoc]

I'm trying to figure out how to read messages from RabbitMQ sent by a third-party service in xml format.
I need to create a DTO class for this message. For example:

opts.ListenToRabbitQueue("emails")
        .DefaultIncomingMessage<SendEmail>();

But how can I use a serialization other than JSON?
Something like UseSystemTextJsonForSerialization but for concrete queue:

opts.ListenToRabbitQueue("emails")
        .UseXmlForSerialization();
        .DefaultIncomingMessage<SendEmail>();

To read messages in xml format:

1. Create a class for serializing XML messages.

public sealed class SystemXmlSerializer : IMessageSerializer
{
    /// <inheritdoc />
    public byte[] Write(Envelope envelope)
    {
        if (envelope.Message is null) throw new InvalidOperationException("Envelope message is null");
        var serializer = new XmlSerializer(envelope.Message.GetType());
        using var writer = new StringWriter();
        serializer.Serialize(writer, envelope.Message);
        return Encoding.UTF8.GetBytes(writer.ToString());
    }

    /// <inheritdoc />
    public object ReadFromData(Type messageType, Envelope envelope)
    {
        if (envelope.Data is null) throw new InvalidOperationException("Envelope data is null");
        var raw = Encoding.UTF8.GetString(envelope.Data);
        var serializer = new XmlSerializer(messageType);
        using var reader = new StringReader(raw);
        return serializer.Deserialize(reader) ?? throw new InvalidOperationException("Message deserialized as null");
    }

    /// <inheritdoc />
    public object ReadFromData(byte[] data)
    {
        throw new NotSupportedException("System.Xml.Serialization requires a known message type");
    }

    /// <inheritdoc />
    public byte[] WriteMessage(object message)
    {
        var serializer = new XmlSerializer(message.GetType());
        using var writer = new StringWriter();
        serializer.Serialize(writer, message);
        return Encoding.UTF8.GetBytes(writer.ToString());
    }

    /// <inheritdoc />
    public string ContentType { get; } = "application/xml";
}

2. Register it.

builder.Host.UseWolverine(options =>
{
    ...
    options.AddSerializer(new SystemXmlSerializer());
    ...
});

3. The message header should contain content_type: application/xml
