Under the remarks section, it says:

The redirect URL is pre-proposed by the library. It does not need to be passed in the constructor

What's this mean? Does it mean the redirect URL is set to a default value?

Strangely I am not able to edit this doc, but just to answer you @jsquire -

The redirect URI is needed for interactive authentication, so that the browser (webview) can return control to the app, and also to pass the authentication code to the app. Each webview (embedded, system) and broker (e.g. Win10's Web Authentication Manager or Authenticator apps on mobile) use a different strategy for getting back from the browser to the app, and as such, there are many redirect URIs formats. MSAL samples for each app type will showcase the redirect URIs. Redirect URIs must always be configured in the AAD portal.

Hi @bgavrilMS. Thanks for your assistance, but please be aware that I'm just triaging the issue from the Azure SDK repository. @sabuncu is the author of the original issue; we'll want to be sure to include them in any activity.

Sounds good. @sabuncu please let me know if you have trouble configuring a redirect uri. The error message from AAD should be very clear if you don't get it right, but they will not give too many details (e.g. what the app redirect URI you used, why it didn't match etc.) for security reasons.

Thank you @bgavrilMS and @jsquire, much appreciated.
