How do I query in SM Parameter Store AMI Alias for a specific version of Amazon ECS-Optimized Amazon Linux 2 AMI

Question

I am trying to query the AMI by lookup up the AMI Alias in SM Parameter Store for a specific version of Amazon ECS-Optimized Amazon Linux 2 AMI. The AMI Alias listed on Marketplace (https://aws.amazon.com/marketplace/server/configuration?productId=9c5eb799-bb6a-4a52-8fda-8e90b3f751f1) is `Ami Alias: /aws/service/marketplace/prod-phaazl5qm6pka/2.0.20220121`

When I query `Name: equals: /aws/service/marketplace/prod-phaazl5qm6pka/2.0.20220121` I get "You do not have any parameters in this region."

I am able to query the "latest" version of the AMI Alias with a query `Name: equals: /aws/service/marketplace/prod-phaazl5qm6pka/latest` and get back exactly on result that has a string value with the expected AMI (currently `ami-0e4efed85dffc2b28` for `us-east-2`).

I want to create some automation that uses the AMI Alias for specific version, and not "latest" and be able to lookup the AMI by region. What am I doing wrong in my query? Or am I maybe missing some permissions or something somewhere?

According to the docs, the /latest is the only public AMI parameters. You can always use the CLI:

```
aws ec2 describe-images --filters 'Name=name,Values=amzn2-ami-ecs-hvm-2.0.20220121-x86_64-ebs' Name=owner-alias,Values=amazon --query Images[*].ImageId --output text --region us-east-2
```
