Ios 如何使用 pushViewController 从 UIHostingController 的 SwiftUI 视图中推送 ViewController

我有一个UIKit应用程序，使用UIHostingController来显示SwiftUI视图.在这个视图中有一个按钮，我想用它导航到另一个视图控制器.How can I push a new viewController from inside this SwiftUI view?(或者更笼统地说:我如何从SwiftUI视图内部调用我的视图控制器中的函数？)

当然，我可以只在SwiftUI中导航视图，但我最想使用UIKit，以便在业务逻辑和UI之间有清晰的分离.

import UIKit
import SwiftUI

class MainViewController: UIViewController {

    var viewModel = ViewModel()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        addView()
    }
    
    func addView() {
            let testView = SwiftUIView(viewModel: viewModel)
            let controller = UIHostingController(rootView: testView)
            addChild(controller)
            controller.view.translatesAutoresizingMaskIntoConstraints = false
            view.addSubview(controller.view)
            controller.didMove(toParent: self)

            NSLayoutConstraint.activate([
                controller.view.widthAnchor.constraint(equalTo: view.widthAnchor),
                controller.view.heightAnchor.constraint(equalTo: view.heightAnchor),
                controller.view.centerXAnchor.constraint(equalTo: view.centerXAnchor),
                controller.view.centerYAnchor.constraint(equalTo: view.centerYAnchor)
            ])
        }

    func navigate() { // how do I call this from inside SwiftUI testView view?
        let otherView = Text("test")
        let nextVc = UIHostingController(rootView: otherView)
        navigationController?.pushViewController(nextVc, animated: true)
    }
}

SwiftUI类似于:

import SwiftUI

struct SwiftUIView: View {
    
    @ObservedObject var viewModel: ViewModel
    
    var body: some View {
         Button {
                    // push new view controller
                } label: {
                    Text("go")
                }
    }
}
