I have a Teams tab app that is using SSO authentication and works well until users open it in pop-out mode. Then the call microsoftTeams.authentication.getAuthToken() fails with the error "Error: App resource defined in manifest and iframe origin do not match".
Is there a way to get the authentication token in a pop-out window?

    Tab SSO shows how to implement Azure AD single sign-on support for tabs.

    • Obtain an access token for the logged-in user using SSO
    • Call a web service - also part of this project - to exchange this access token
    • Call Graph and retrieve the user's profile
    • Bot, ME SSO Bot Framework v4 bot using Teams authentication

    The below sample app talks about the Teams Tab, Bot, ME - search, action, linkunfurl SSO with C#.
