Properties

Name	Type	Description
assumeRoleAction	string	When this Principal is used in an AssumeRole policy, the action to use.
grantPrincipal	IPrincipal	The principal to grant permissions to.
policyFragment	PrincipalPolicyFragment	Return the policy fragment that identifies this principal in a Policy.
principalAccount?	string	The AWS account ID of this principal.
