SwiftyDropbox SwiftUI iOS

I found the following issue regarding SwiftyDropbox and SwiftUI: 

I just removed the ScrollView which made Problems, and it seems to work:

struct ContentView : View {
    @State var isShown = false
    
    var body : some View {
            VStack {
                Text("HI!")
                Button(action: {
                    self.isShown.toggle()
                }) {
                    Text("Dropbox....")
                }
                DropboxView(isShown: $isShown)
            }
    }
}


struct DropboxView: UIViewControllerRepresentable {
    typealias UIViewControllerType = UIViewController
    
    @Binding var isShown : Bool

    func updateUIViewController(_ uiViewController: UIViewController, context: Context) {
        if isShown {
            DropboxClientsManager.authorizeFromController(UIApplication.shared,
            controller: uiViewController,
            openURL: { (url: URL) -> Void in
                UIApplication.shared.open(url, options: [:], completionHandler: nil)
            })
        }
    }

    func makeUIViewController(context _: Self.Context) -> UIViewController {
        return UIViewController()
    }
}

--> the authorisation page of Dropbox opens and I can enter my credentials.

My next Problem: when I check the DropcoxClientsManager afterwards, it still contains nil

if DropboxClientsManager.authorizedClient != nil {
