I would like to know it is possible to embed reports/dashboards into a web app WITHOUT a Premium license --- FOR Power BI Users?? (do not want to use publish to web)
Embedding with Power BI users
Embedding for Power BI users is the functionality that has been available with the Power BI service. You can continue to embed content from the Power BI service into your applications using the REST API. This requires that the end user of your application sign into the Power BI service when you want to view your content in the application. Once your end user signs in, they will only have access to dashboards and reports that have been shared with them in the Power BI service. For more information on how to do this, see the following.
