"HandleMessage" is not callback. What is the reason?

hi,
The "OnStartConfimingEvent” method of "MyInjectableRabbitMqConsumer" of this class works normally, but "HandleMessage" is not callback. What is the reason?

private Task HandleMessage(IMessage message, MessageReceivedInfo info,
CancellationToken token)
{
Logger.LogDebug($"Received untyped message: {message.Body}");

        return Task.FromResult(AckStrategies.Ack);
    }
