role
Parameters
value
The Amazon Resource Name (ARN) for the IAM role that you want to associate with the group. A group role primarily declares a preferred role for the credentials that you get from an identity pool. Amazon Cognito ID tokens have a cognito:preferred_role claim that presents the highest-precedence group that a user belongs to. Both ID and access tokens also contain a cognito:groups claim that list all the groups that a user is a member of.
