Is it fine to use the root view controller of the UIWindow to present a view controller in a SwiftUI Project?

I am trying to embed the CNContactPickerViewController in a SwiftUI project. I managed to show the controller by using the UIViewControllerRepresentable but I am showing the controller in the presentation mode and animations do not work well.

Code Block 
Button(action: {
	 self.isPresented = true
}) {
	 Text("Present")
}.sheet(isPresented: $isPresented) {
	 TestView()
}

Instead of embedding the CNContactPickerViewController, which is a UIKit component indeed, I tried to present the picker within the root view controller as shown below.

Code Block 
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
		var window: UIWindow?
		static func present() {
				
				let root = UIApplication.shared.windows.first?.rootViewController
				let viewController = CNContactPickerViewController()
				root?.present(viewController, animated: true, completion: nil)
		}
		func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
				let contentView = ContentView()
				// Use a UIHostingController as window root view controller.
				if let windowScene = scene as? UIWindowScene {
						let window = UIWindow(windowScene: windowScene)
						window.rootViewController = UIHostingController(rootView: contentView)
						self.window = window
						window.makeKeyAndVisible()
				}
		}
...

I show the CNContactPickerViewController as a piece of the root view controller by calling the SceneDelegate's present method within the SwiftUI component.

Code Block 
Button(action: {
								SceneDelegate.present()
}) {
								Text("Present")
}

I know it isn't a good practice but works perfect and embedding it into the SwiftUI with the UIViewControllerRepresentable does not give me good results because it makes a flash effect, animation hangs while it is showing up.

I wonder the method that I've explained above is okay for Apple? Does it violate terms? Is it allowed to directly manipulate the root view controller? I have never encountered with this kind of method so I have no idea if I am doing something wrong.
