How to use AWS System Manger with Amplify

Question

I have an AWS Amplify App and I am storing secrets in the AWS System Manager parameter store. According to the documentation, I followed this syntax /amplify/{your_app_id}/{your_backend_environment_name}/{your_parameter_name} and created this parameter /amplify/abcdefgh1234/dev/MY_PARAM. How do I use MY_PARAM in amplify.yaml? When I use MY_PARAM as stated below, I get empty values. I have added /amplify/abcdefgh1234/dev/MY_PARAM in environment variables section in amplify app setting.

version: 1
frontend:
  phases:
    preBuild:
      commands:
        - echo ${secrets.MY_PARAM}
        - echo $secrets

Role used in Amplify was missing permissions of SSM. I have added the below actions to the existing amplify role and it was able to fetch the parameters

 "ssm:PutParameter",
 "ssm:GetParametersByPath",
 "ssm:GetParameters",
 "ssm:GetParameter"
