How do I configure the MQTT (AWS IoT) test console for an Alexa skill invocation?

Hi.

I have followed the following guide successfully except for testing with AWS IoT Core (subscribe to a topic)

What I have done is the following:

1. My skill can supposedly be integrated into AWS:

2. In IAM I have a role that I have used to test the AWS examples of freertos with a microcontroller:

3. In that role, I have Edit trust relationship and I have added the AWS Lambda Execution Role ARN:

4. I go to AWS IOT Test and I subscribe to all the topics (#)

5. I never frames the plots that should come and go from the tests I do from the Alexa dev console.

Any comment or suggestion is welcome

Regards
