Thanks for the info. It helped. I could resolve this issue.
However when creating a dashboard on the target account I am seeing this issue:
InvalidParameterValueException: An error occurred (InvalidParameterValueException) when calling the CreateDashboard operation: Principal arn:aws:quicksight:us-west-2:280181752709:user/default/AWSReservedSSO_full_88f15623f8a08ffa/***@abc.com is part of a different account
How do I resolve this?
