UINavigationControllerの階層にあるTransitionStyleがscrollのPageViewControllerをスワイプバックで戻りたい

UINavigationControllerの階層にあるTransitonStyleがscrollのPageViewControllerをスワイプバックで戻りたい

UINavigationControllerの階層にあるPageViewControllerがTransitionStyleがpageCurlのときはスワイプパックで戻れるのですが、TransitionStyleをscrollにするとスワイプバックが反応せずにViewが動いてしまいます
これをTransitonStyleがscrollの状態でもスワイプバックできるようにしたいです

該当のソースコード

Swift
1class TestPageViewController: UIViewController {
2    
3    private var controllers: [UIViewController] = []
4    private var pageViewController: UIPageViewController!
5
6    override func viewDidLoad() {
7        super.viewDidLoad()
8        
9        let colors: [UIColor] = [.red, .orange]
10        controllers = colors.map { color in
11            let vc = UIViewController()
12            vc.view.backgroundColor = color
13            return vc
14        }
15
16        self.pageViewController = UIPageViewController(transitionStyle: .scroll, navigationOrientation: .horizontal, options: nil)
17        self.pageViewController.setViewControllers([self.controllers[0]], direction: .forward, animated: true, completion: nil)
18        self.pageViewController.dataSource = self
19        self.pageViewController.delegate = self
20        self.addChild(self.pageViewController)
21        self.view.addSubview(self.pageViewController.view!)
22        
23    }
24    
25    
26
27}
28
29extension TestPageViewController: UIPageViewControllerDataSource {
30
31    func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController? {
32        
33        if let index = controllers.firstIndex(of: viewController),
34            index > 0 {
35            return controllers[index-1]
36        } else {
37            return nil
38        }
39    }
40
41    func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController? {
42        
43        if let index = controllers.firstIndex(of: viewController),
44            index < controllers.count-1 {
45            return controllers[index+1]
46        } else {
47            return nil
48        }
49    }
50
51    func presentationCount(for pageViewController: UIPageViewController) -> Int {
52        return controllers.count
53    }
54    
55}
56
57extension TestPageViewController: UIPageViewControllerDelegate {
58    
59}

追記このViewControllerから上記のPageViewControllerへ遷移してます

class FirstViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }
    
    @IBAction func tap(_ sender: Any) {
        let testVC = TestPageViewController.instantiate()
        navigationController?.pushViewController(testVC, animated: true)
    }

}
