@mehdi-parvizi There are a few important things you need to address in your code:

1- Environment Variables: Please replace the hardcoded IP and port for connecting to the backend gpt-app with environment variables.

2- Progress Bar: Please implement a progress bar. Currently, when the user clicks the "Generate" button, there is no feedback until the ZIP file is downloaded. I would like the progress bar to notify the user to wait while the ZIP file is being downloaded.

3- IAM Endpoint: Please recheck the IAM endpoint. When we go to IAM and click on iam_user, I expect it to be set to true, but in the final result, it is set to false. This issue also applies to iam_group.
