Setting up the IAM policy for asynchronous synthesis

In order to use the asynchronous synthesis functionality, you will need an IAM policy that allows the following:

• use of new Amazon Polly operations

• writing to the output S3 bucket

• publishing to the status SNS topic [optional]

The following policy grants only the necessary permissions required for asynchronous synthesis and can be attached to the IAM user.
