How to prevent screenshot of opened document in UIDocumentInteractionController?

Question

everyone! I'm building an app for making documents(UIKit). And after user fill all the info, the app presents a filled document. I use UIDocumentInteractionController to present it on full screen and I would like to prevent making screenshooting of that screen. That's how I open a document

let docOpener = UIDocumentInteractionController.init(url: path)
                    docOpener.delegate = self
                   docOpener.presentPreview(animated: true)

extension PreviewVC: UIDocumentInteractionControllerDelegate {
    func documentInteractionControllerViewControllerForPreview(_ controller: UIDocumentInteractionController) -> UIViewController {
        return self
    }
    
    func documentInteractionControllerViewForPreview(_ controller: UIDocumentInteractionController) -> UIView? {
        return self.view
     
    }
    
    func documentInteractionControllerRectForPreview(_ controller: UIDocumentInteractionController) -> CGRect {
        return self.view.frame
    }
}

I've tried to use ScreenshotPreventing-iOS framework and also this extension

  extension UIView {
    func makeSecure() {
        DispatchQueue.main.async {
            let field = UITextField()
            field.isSecureTextEntry = true
            self.addSubview(field)
            field.centerYAnchor.constraint(equalTo: self.centerYAnchor).isActive = true
            field.centerXAnchor.constraint(equalTo: self.centerXAnchor).isActive = true
            self.layer.superlayer?.addSublayer(field.layer)
            field.layer.sublayers?.first?.addSublayer(self.layer)
        }
    }

That's works, but it hides only UIView from screenshots. As I understood the UIDocumentInteractionController has no view inside and don't allow to work somehow with its layer that shows opened document. So also i've tried to put a UIView under the UIDocumentInteractionController and hide it together but it doesn't work. Please help me to hide info somehow. Thanks
