You need a production-appropriate custom IAM role and want to communicate its development status; this is the first version of the role. What practices should you follow?

When creating a custom IAM role for production, it's crucial to use permissions with a 'supported' support level. This ensures the permissions are stable and won't be deprecated without notice, which is essential for production environments. Setting the role stage to ALPHA while testing correctly indicates that the role is in its earliest development phase and is not yet stable or ready for broad use. Using 'BETA' for the role stage implies a more stable, but still pre-production, state, which isn't accurate for the first version under initial testing. Using 'testing' for permission support level is incorrect because 'testing' permissions are experimental and subject to change or removal, making them unsuitable for production-bound roles.
