Feature Request: fetch parameter from AWS Systems Manager cross account

[mwiede]

I would like to fetch a ssm parameter from another account.

I tried with given arn as it does work with secretsmanager, but this leads to error invalid port ":parameter" after host

I used ref+awsssm://arn:aws:ssm:eu-central-1:12345:parameter/path/to/parameter

As stated in document https://docs.aws.amazon.com/cli/latest/reference/ssm/get-parameter.html#options for accessing parameters from shared account, we need ARN as name.
