I Have created application in angular 4 and iam trying to embed tableau dashboards in the application.
embeded tableau dashboard is prompting for sign in.
<iframe src="https://tableauserver/view/dashboard/12345" sandbox="allow-top-navigation allow-same-origin allow-scripts allow-forms allow-popups"></iframe>
But actully when we open same link in the new tab then its getting authenticated using sso and open the dashboard. tablue link in addressbar
when we open the tableau dashboards first in one tab and then in new tab we open the application then the dashboards are displaying.
can any one suggest how to do this sso authentication with in iframe
