+/// Presents a web authentication session that will display the user's account settings page.
+///
+/// A web authentication session is used so that the same session used for login is available
+/// meaning that the user doesn't need to sign in again. `SFSafariViewController` doesn't
+/// have access to this session, and for some reason `prefersEphemeralWebBrowserSession`
+/// isn't sharing the session back to Safari.
