Push to next View on button click from SwiftUI View which is inside UITableView Cell

Question

I have one view named WelcomeView in SwiftUI which is having next button. so on click of next button I want to push my view to other view using NavigationLink.

Problem that I am facing is I have to render my WelcomeView inside UITableView Cell in Swift file. so when I render that page inside UITableView Cell, and click on join button it is pushing my view to next view but inside UITableViewCell only.

I want to show my next view in whole page and not inside table cell.

TableFile (Swift)

 public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

   let cell = theTableview.dequeueReusableCell(withIdentifier: "SessionCardCell", for: indexPath) as! HostingTableViewCell<WelcomeView>
         
  cell.host(WelcomeView(), parent: self)
            
  return cell

}

Cell Class


class HostingTableViewCell<Content: View>: UITableViewCell {

    private let hostingController = UIHostingController<Content?>(rootView: nil)

    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        hostingController.view.backgroundColor = .clear
    }
    
    override func sizeThatFits(_ size: CGSize) -> CGSize {
        return CGSize(width: ScreenSize.width, height: 100 * ScreenSize.width/375)
        // return hostingController.sizeThatFits(in: CGSize(width: ScreenSize.width, height: 250))
    }
    
    override func layoutSubviews() {
        super.layoutSubviews()
        hostingController.view.frame.size = CGSize(width: ScreenSize.width, height: 100 * ScreenSize.width/375)//self.sizeThatFits(bounds.size)
    }
    
    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    func host(_ view: Content, parent: UIViewController) {
        
        self.hostingController.rootView = view
        self.hostingController.view.invalidateIntrinsicContentSize()
        
        let requiresControllerMove = hostingController.parent != parent
        if requiresControllerMove {
            parent.addChild(hostingController)
        }
        
        if !self.contentView.subviews.contains(hostingController.view) {
            self.contentView.addSubview(hostingController.view)
            hostingController.view.translatesAutoresizingMaskIntoConstraints = false
            hostingController.view.leadingAnchor.constraint(equalTo: self.contentView.leadingAnchor).isActive = true
            hostingController.view.trailingAnchor.constraint(equalTo: self.contentView.trailingAnchor).isActive = true
            hostingController.view.topAnchor.constraint(equalTo: self.contentView.topAnchor).isActive = true
            hostingController.view.bottomAnchor.constraint(equalTo: self.contentView.bottomAnchor).isActive = true
        }
        
        if requiresControllerMove {
            hostingController.didMove(toParent: parent)
        }
    }
}

WelcomeView (SwiftUI root View)

struct WelcomeView: View {

 @State var pushToNextScreen : Bool = false

 var body: some View {
     NavigationView {
        VStack {
            Button {
                //action
                self.pushToNextScreenRoot = true
            } label: {
                Text("Join")
           }

           NavigationLink(destination: SecondView(), isActive: self.$pushToNextScreenRoot) { }

        }//vstack
     }//navigation view
  }
}
