title: Cannot publish to azure directory
body: <p>I am using Microsoft Graph API to send messages to private users in Microsoft Teams. I registered an App in Azure Active Directory, gave proper permissions and called the API and was able to successfully send the message. 
  My question is what would be the most efficient way to deliver this integration to different clients? Do we have to register an App in every azure directory of the client individually, or is there a way I can publish the app that I have created with all the API permissions required and the administrators can install the app in their azure directory </p>
