I have an Outlook AddIn that uses an internally-hosted .aspx page in the task pane. It was built in Visual Studio 2022 and does not currently use MSAL at all. I am struggling to figure out what changes I need to make in order to use Nested App Authentication. The examples I've been able to find so far bear no resemblance whatsoever to my current application.

Is it even possible to upgrade an add-in like this to use NAA or am I looking at a total rewrite?
