Thanks again!
We don't have the UISceneStoryboardFile in the configuration because we initialize our ViewController in scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) (see the last code block).
The second UISceneConfiguration is used in our tests. But I also tried without it and it didn't work either.
