Editing a service-linked role for AWS End User Messaging

AWS End User Messaging does not allow you to edit the AWSServiceRoleForSocialMessaging service-linked role. After you create a service-linked role, you cannot change the name of the role because various entities might reference the role. However, you can edit the description of the role using IAM. For more information, see Editing a service-linked role in the IAM User Guide.
