Convert RabbitMQ messages into List using C# in Console Application

I need parse array payload into list model for other post data send message but i still get result array not list string

var factory = new ConnectionFactory
{
    HostName = "localhost"
};
 
var connection = factory.CreateConnection(); 
using var channel = connection.CreateModel(); 
channel.QueueDeclare("email_confirmation_notifications", exclusive: false, autoDelete: false);
 
var consumer = new EventingBasicConsumer(channel); 
string[] splitItems = null; 
consumer.Received += (model, eventArgs) =>
{
    var body = eventArgs.Body.ToArray();
    var message = Encoding.UTF8.GetString(body);
    channel.BasicAck(eventArgs.DeliveryTag, false);
    Console.WriteLine($"Notification message received: {message}");
};
 
channel.BasicConsume(queue: "email_confirmation_notifications", autoAck: true, consumer: consumer); 
Console.ReadKey();
