404 Not Found - nginx/1.26.1

Follow all steps described at https://docs.aws.amazon.com/whitepapers/latest/migrating-magento-open-source-adobe-commerce-to-aws/deployment-steps.html
and apparently everything worked as expected, ending the process with the message below:

NOTE! It takes about ~15 minutes for Magento to bootstrap
so please wait for a while before trying out the installation.
Webshop will be available at: https://dzat3rcy0hopb.cloudfront.net/ once ready.

However, even waiting for more than an hour and when accessing https://dzat3rcy0hopb.cloudfront.net/ I get the page:
404 Not Found - nginx/1.26.1

Is there any procedure beyond what is described at https://docs.aws.amazon.com/whitepapers/latest/migrating-magento-open-source-adobe-commerce-to-aws/deployment-steps.html
to make magento work correctly? If so, what are the next steps to make the entire environment functional?
