"In this post https://aws.amazon.com/blogs/compute/adding-approval-notifications-to-ec2-image-builder-before-sharing-amis-2/?trk=global_employee_advocacy&sc_channel=sm&advocacy_source=everyonesocial&es_id=38f88ae532, we will walk through the steps to enable approval notifications before AMIs are shared with other AWS accounts. Image Builder supports automated image testing using test components. The recommended best practice is to automate test steps, however situations can arise where test steps become either challenging to automate or internal compliance policies mandate manual checks be conducted prior to distributing images. In such situations, having a manual approval step is useful if you would like to verify the AMI configuration before it is shared to other AWS accounts or an AWS Organization."
