Allow SSO Auth for web content tile iframe in PowerBI Service

Want to be able to support surfacing content from internal application within an iframe in PowerBI Service.

example html:

 iframe src=https://crocs.XXXXXXXXX.com/..... 

> The above URL is in internal link that is configured with single sign on - using the same authentication as powerbi and any other internal app at our company

Current Behavior when attempting this:

• The web content tile Iframe shows as an empty square
• network response throws a group not accessible error:

Failed to load resource: the server responded with a status of 401 () - https://wabi-west-us-b-primary-redirect.analysis.windows.net/metadata/app?preferReadOnlySession=true&cmd=dashboard.........

Expected Behavior:

• Given the website we are trying to surface utilizes the same authentication method - we expect that to be authenticated during the same or subsequent session
• The iframe should be able to show all necessary info
