Documentation: Push Updated 3p Packages to Production

[AMZN-Gene]

As a dev I'm unsure how to push an updated 3p package to production. For example, if I update the AWS SDK from version 1 to version 2, what's the process for pushing that v2 package to all users worldwide.

The 3p-package-scripts repo describes a python script called upload_all_packages for pushing a package into an S3 bucket.
python3 ./Scripts/upload_all_packages.py --bucket_name my-s3-bucket-name

However, the production bucket is located at s3://o3de-prod-3p-packages but if someone doesn't have write permissions, what steps should be taken?

Is it automated, or require does it require a human signoff?

Is there a GHI I should fill out to begin the process?

Do I reach out to a special-interest-group on Discord for someone who has access?
