Quicksight embedding SDK - get dashboard ID

We have a web app in which we embedded both the Quicksight console (for building) and dashboards (for visualization). Once a user build a dashboard in the embedded console, he needs to copy the dashboardID to a configuration in our web app and we used that id to be displayed in the dashboards embedding (visualization part). Is there any way of obtaining the dashboard ID from the embedded console iframe? I tried many ways, including viewing the frame source but this only works manually (not programatically via Javascript) due browsers security reasons.

Thanks!
