Overview: User objects represent people in the real world; their hopes, their dreams, and their current presence information.
NOTE: the nonce is only good for one check and then it's invalidated.
App-Scoped IDs: To protect user privacy, users have a different ovrID across different applications. If you are caching them, make sure that you're also restricting them per application.
This class provides methods to access information about the
ovrUserHandle. It allows you to retrieve a user's ID, access token, and org-scoped ID, as well as their friends list and recently met users. Additionally, it provides methods to launch various flows such as blocking, unblocking, reporting, and sending friend requests. It's useful when you need to manage user relationships or perform actions that require user authentication within your application.
