In either case, we'll just grab the first connected UIScene and proceed.
-         * - Otherwise, we're either in a SwiftUI app that _does_ call SentrySDK.start at the recommended time (SwiftUIApp.init), or there is a more complicated initialization procedure in a UIKit app that we can't automatically detect, and the app will need to call SentrySDK.feedback.showWidget() at the appropriate time, the same as how SwiftUI apps must currently do once they've connected a UIScene to their UIApplicationDelegateAdaptor.
