How do I get the arn of the assumed user who is going to deploy the CDK stack in CDK? The format that's in arn:aws:sts::accountID:assumed-role/AWSReservedSSO_AWSAdministratorAccess_xxxxxxxxxxxxxxx/user@email.com
e.g. the arn that appears when i run aws sts get-caller-identity
I tried to retrieve from the cdk library iam.Role.??? construct but none seems to have related to assumed role
