Deeper integration with Teams by using custom App and SAML2

Using the Microsoft Teams App Studio we can add sites that are packaged together as a set of tabs accessed by an icon on the sidebar of Teams. When using SAML2 authentication with Microsoft Azure Active Directory, users of the site is presented with a page to enter an email address, and then are redirected to login.microsoftonline.com to complete thier orginizational login. This works great in the web browser and also works in the Teams web app. In the Teams desktop app however the redirect fails becuase of iframe security built into the login.microsoftonline.com site. Microsoft has a solution, they support pop-up login page that will allow the site to not require the redirect.

It would be nice (and easy to implement) to have a check box in the SAML2 integration screen that says to load by pop-up instead of a redirect.

Side note, since this is a Teams Integration suggestion. There is a Teams Javascript library and initilizer that enables supported communication between the embedded site and the Teams window hosting the view. It would be nice to have a checkbox in the admin section that "Enable Microsoft Teams App Integration" that would turn on the addition of this javascript in the head of the loaded pages for Aha!'s applications.
