Currently, I’m writing a program that receives messages from RabbitMQ streams, and I want to delete the messages after they have been consumed. Is this possible?

var streamSystem = await StreamSystem.Create(new StreamSystemConfig());

        await streamSystem.CreateStream(new StreamSpec("csv-stream")
        {
            MaxLengthBytes = 1_048_576
        });

        Console.WriteLine("Starting consuming...");
        var consumer = await Consumer.Create(new ConsumerConfig(streamSystem, "csv-stream")
        {
            OffsetSpec = new OffsetTypeFirst(),
            MessageHandler = async (stream, _, _, message) =>
            {
                // Receive and convert message to string
                var receivedData = Encoding.UTF8.GetString(message.Data.Contents);

                // Convert string to CSV format
                                
                await Task.CompletedTask;
            }
        });

        Console.WriteLine(" Press any key to exit");
        Console.ReadKey();

        await consumer.Close();
        await streamSystem.Close();

So, I try to use await consumer.Ack(message); but it’s didn’t work.
