Explanation:
Permission policies provide a centralized way to configure and manage a set of permissions that applies
to only a subset of users or groups in a web application.
Note: An app for SharePoint requests the permissions that it needs during installation from the user
who is installing it. The developer of an app must request, through the app manifest file, the permissions
that the particular app needs to be able to run. An app must be granted permissions by the user who is
executing the app.
