Exemption Request

Not sure if README and test is needed since this just add supported parameters of codepipeline actions's manual approval action

Hi @pitayapj, for all new features we require README updates as well as at least unit tests. Since new properties are being added I think that integration tests to ensure that the deployment is successful is appropriate here too. For the README please include a code example that uses the new properties and describe what they do or add the properties to an existing code example with an additional short description.
