You can run the describe_dashboard_permissions to get the owners: describe-dashboard-permissions — AWS CLI 1.22.101 Command Reference
Sample syntax: aws quicksight describe-dashboard-permissions --dashboard-id <<dashboard-id>> --aws-account-id <<account-id>> --region us-east-1
Sample response:
{
“Principal”: “arn:aws:quicksight:us-east-1::user/default/Administrator/wangzyn-Isengard”,
“Actions”: [
“quicksight:DescribeDashboard”,
“quicksight:ListDashboardVersions”,
“quicksight:UpdateDashboardPermissions”,
“quicksight:QueryDashboard”,
“quicksight:UpdateDashboard”,
“quicksight:DeleteDashboard”,
“quicksight:DescribeDashboardPermissions”,
“quicksight:UpdateDashboardPublishedVersion”
The principal is a user or a group. If you see “quicksight:DeleteDashboard” action in the actions list, then this principal should be the owner.
