8.  Information needed for an Authorization Token
 Client ID – Client ID is used by the application to identify themselves to
the users that they are requesting permissions from.
 Client Key – The client secret key is sent along with a Client ID when
authenticating to Azure AD to call a web API.
 Resource Uri – The resource Uri to the Power BI resource to be
authorized. [https://analysis.windows.net/powerbi/api]
 Authority Uri – The authority Uri is an Azure resource that takes a client
id to get an access token.
[https://login.windows.net/common/oauth2/authorize/]
 Redirect Url – A Redirect Url for the web app url. The Azure AD service
redirects back to the web app url with an authentication code.
