Using AppConfig feature flags extension problem

Hello! To troubleshoot the issue you're having with AppConfig deployment events not being sent to your SNS topic, you can follow these steps:

1. Ensure the SNS topic exists and is configured correctly.
2. Ensure that the SNS subscription is confirmed.
3. Confirm that the IAM role associated with the AppConfig has the required permissions to publish to the SNS topic.
4. Ensure the extension is attached to the correct AppConfig environment.
5. Check CloudWatch Logs for any errors related to AppConfig deployments and SNS topics.
6. Check the deployment history in the AppConfig console to make sure deployment events are being generated.
7. Test sending a message to your SNS subscription endpoint using the "Publish message" option in SNS on the subscription page
