Navigation Controller Delegate not working

[phuongddx]

    case root
}

final class CommunitiesCoordinator: NavigationCoordinator<CommunitiesRoute> {
    init() {
        super.init(initialRoute: .root)
        delegate = RootNavigationControllerDelegateWrapper()
    }

    override func prepareTransition(for route: CommunitiesRoute) -> NavigationTransition {
        switch route {
            case .root:
                let rootVc = CommunitiesViewController()
                return .push(rootVc)
        }
    }
}

final class RootNavigationControllerDelegateWrapper: NSObject,
                                                     UINavigationControllerDelegate {
    func navigationController(_ navigationController: UINavigationController,
                              willShow viewController: UIViewController,
                              animated: Bool) {
        print("🚀 Will show: \(type(of: viewController))")
    }
    
    func navigationController(_ navigationController: UINavigationController,
                              didShow viewController: UIViewController,
                              animated: Bool) {
        print("✅ Did show: \(type(of: viewController))")
    }
}

I have simple routing like that, but look like delegate func not to be call, could you guys help me check on it?
