Cannot Update Navigation menu items at Runtime

Describe the bug

I am trying to add few Items based on configuration after the user logs in but the issue is I can see that the item is been added to the navigation menu but for some reason its not shown in the layout.

I can tell that the property is being changed but its not updating in the UI.

It works fine if I add the NavigationViewItem at constructor but not when i use a Command or for starters using the default events like for example NavigationView_PaneOpened

        private void NavigationView_PaneOpened(NavigationView sender, RoutedEventArgs args)
        {
            if (_isPaneOpenedOrClosedFromCode)
                return;

            NavigationView.MenuItems.Clear();
            NavigationView.MenuItems.Add(new NavigationViewItem("SamplePage", SymbolRegular.Home24, typeof(SamplePage)));

            _isUserClosedPane = false;
        }

To Reproduce

Try adding a NavigationViewItem after page load like in event or Relay Command ,etc

here is old data

I can see that the item is added in navigation item

after clearing the list and adding new items:

but its not appearing in the main window navigation

Expected behavior

The NavigationViewItem Should be added in Navigation menu items list
