Register Integration with CodePipeline

I would like to register integration (action provider) with code pipeline. May I know which support plan need to be activated so I can raise a ticket to CodePipeline service team so new action provider can be registered initially for testing purpose and then later on for public.

I have been referring below documentation for registration of new action provider. https://docs.aws.amazon.com/codepipeline/latest/userguide/action-types.html
