To access parameter store in a different CDK region, follow the steps below:

1. Import the AWS SDK for the appropriate programming language you are using.

   import * as AWS from 'aws-sdk';
   

2. Create an instance of the AWS SDK with the region you want to access.

   const ssm = new AWS.SSM({ region: 'us-west-2' });
   

3. Use the getParameter method to retrieve a specific parameter from the parameter store.

   const response = await ssm.getParameter({ Name: 'my-parameter' }).promise();
   const parameterValue = response.Parameter?.Value;
   

4. Optionally, you can also use the putParameter method to store a parameter in the parameter store.

   await ssm.putParameter({ Name: 'my-parameter', Value: 'my-value', Type: 'String' }).promise();
   

Note: It is important to ensure that your IAM role has the appropriate permissions to access the parameter store in the region you want to access.
