executionRoleName

The name of the IAM execution role to use to create the StackSet. If you do not specify an execution role, CloudFormation uses the AWSCloudFormationStackSetExecutionRole role for the StackSet operation.

Specify an IAM role only if you are using customized execution roles to control which stack resources users and groups can include in their StackSets.

Valid only if the permissions model is SELF_MANAGED.
