The Seamless SharePoint Add-In requires an authentication using the Microsoft Identity platform. The Microsoft Authentication Library (MSAL) enables developers to acquire tokens from the Microsoft identity platform in order to authenticate users and access secured web APIs.
This authentication requires that you
