Defines different values for how to handle interactive login, in case the requested tokens cannot be acquired without user interaction.

• Popup - Default. Interactive login is done by opening a popup dialog window. This is the recommended mode because it does not take the user away from what the user was trying to accomplish.
• Redirect - The browser will be redirected to the login service. The user will be redirected back to the URI specified in the RedirectUrl property on the BlazoradeMsalOptions class.
• Disabled - No interactive login will be performed.
