Pull down gesture Not working in UIpageViewController

I'm Presenting UIPageViewController, each page has UItableView. Pull-down gesture to dismiss not working in UIPageViewControllerTransitionStyle.scroll, but it's working fine in pageCurl style.

PageViewController


class PageViewController: UIPageViewController, UIPageViewControllerDataSource {
   
  let pages: [UIViewController]
  init(pages: [UIViewController]) {
    self.pages = pages
    super.init(transitionStyle: .scroll, navigationOrientation: .horizontal, options: nil)
  }
   
  required init?(coder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
  }
   
  override func viewDidLoad() {
    super.viewDidLoad()
    self.dataSource = self
    if let viewController = self.pages.first {
      self.setViewControllers([viewController], direction: .forward, animated: true)
    }
  }
   
  //MARK: UIPageViewControllerDataSource
  func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController? {
    guard let index = self.pages.firstIndex(of: viewController), index + 1 < tabVsViewController.count else {
      return nil
    }
    return self.pages[index + 1]
  }
   
  func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController? {
    guard let index = self.pages.firstIndex(of: viewController), index - 1 >= .zero else {
      return nil
    }
    return self.pages[index - 1]
  }
}
       let bottomView = PageViewController(pages: viewControllers)
       bottomView.preferredContentSize = CGSize(width: self.view.bounds.width ?? 0.0, height: 300.0)
       bottomView.modalPresentationStyle = .formSheet
       let sheetPresentation = bottomView.sheetPresentationController
       sheetPresentation?.detents = [.medium(), .large()]
       sheetPresentation?.selectedDetentIdentifier = .medium
       sheetPresentation?.preferredCornerRadius = 20.0
       sheetPresentation?.prefersGrabberVisible = true
       self.present(bottomView, animated: true, completion: nil)
