I’ve noticed the identifier is dashboard id. Also, can we view which users/user groups accessed the dashboard?
Currently this is not available. Since Quicksight supports usage of same name across multiple dashboards and dashboard-id is used as key to differentiate, the same is being displayed on CloudWatch.
Alternatively, you try creating custom dashboard in Quicksight by retrieving the CloudWatch Data and combining with Dashboard information on Quicksight.
