@StateObject var authentication = Authentication()

var body: some Scene {
    WindowGroup() {
        
        if authentication.isValidated {
            ContentView()
                .environmentObject(authentication)
        } else {
            HomeView()
                .environmentObject(authentication)
        }
    }
}
