Unsure about creating a Multi Page App?

[NopeImNotHere]

Hey,

I've been trying to create a sort of Multi Page App but have been unable to actually navigate to each of my windows.
I have seen this Discussion, but it has not gotten me to any result in V2.
At least when trying the Solution by @tznind in that Discussion, the other created Window does not display.

Which is why I'm asking if there is any bare-bones Example for switching between multiple window's?

Thanks for the help in advance

Here is a multi page demo where main Toplevel is written using TerminalGuiDesigner targetting v2.

Program.cs

using Terminal.Gui;
using YourNamespace;

Application.Init();

Application.Run(new MyTop());
Application.Shutdown();

MyTop.cs

public partial class MyTop
{
    private Window win1 = new Window() { Title = "Window1" ,Y=1, Width = Dim.Fill(),Height = Dim.Fill()};
    private Window win2 = new Window() { Title = "Window2", Y = 1, Width = Dim.Fill(), Height = Dim.Fill() };
    private Window win3 = new Window() { Title = "Window3", Y = 1, Width = Dim.Fill(), Height = Dim.Fill() };
    public MyTop() {

        InitializeComponent();

        CanFocus = true;

        window1MenuItem.Action = () => SetupWindow(1);
        window2MenuItem.Action = () => SetupWindow(2);
        window3MenuItem.Action = () => SetupWindow(3);

        exitMenuItem.Action = () => Application.RequestStop();
    }

    private void SetupWindow(int windowNumber)
    {
        Remove(win1);
        Remove(win2);
        Remove(win3);

        switch (windowNumber)
        {
            case 1: Add(win1);
                break;
            case 2: Add(win2);
                break;
            case 3: Add(win3);
                break;
        }
    }
}

MyTop.Designer.cs

public partial class MyTop : Terminal.Gui.Toplevel {
    
    private Terminal.Gui.MenuBar menuBar;
    
    private Terminal.Gui.MenuBarItem fileF9Menu;
    
    private Terminal.Gui.MenuItem exitMenuItem;
    
    private Terminal.Gui.MenuBarItem windowMenu;
    
    private Terminal.Gui.MenuItem window1MenuItem;
    
    private Terminal.Gui.MenuItem window2MenuItem;
    
    private Terminal.Gui.MenuItem window3MenuItem;
    
    private void InitializeComponent() {
        this.menuBar = new Terminal.Gui.MenuBar();
        this.Width = Dim.Fill(0);
        this.Height = Dim.Fill(0);
        this.X = 0;
        this.Y = 0;
        this.Visible = true;
        this.Arrangement = Terminal.Gui.ViewArrangement.Fixed;
        this.Modal = false;
        this.TextAlignment = Terminal.Gui.Alignment.Start;
        this.menuBar.Width = Dim.Fill(0);
        this.menuBar.Height = 1;
        this.menuBar.X = 0;
        this.menuBar.Y = 0;
        this.menuBar.Visible = true;
        this.menuBar.Arrangement = Terminal.Gui.ViewArrangement.Fixed;
        this.menuBar.Data = "menuBar";
        this.menuBar.TextAlignment = Terminal.Gui.Alignment.Start;
        this.fileF9Menu = new Terminal.Gui.MenuBarItem();
        this.fileF9Menu.Title = "_File (F9)";
        this.exitMenuItem = new Terminal.Gui.MenuItem();
        this.exitMenuItem.Title = "Exit";
        this.exitMenuItem.Data = "exitMenuItem";
        this.fileF9Menu.Children = new Terminal.Gui.MenuItem[] {
                this.exitMenuItem};
        this.windowMenu = new Terminal.Gui.MenuBarItem();
        this.windowMenu.Title = "Window";
        this.window1MenuItem = new Terminal.Gui.MenuItem();
        this.window1MenuItem.Title = "Window 1";
        this.window1MenuItem.Data = "window1MenuItem";
        this.window2MenuItem = new Terminal.Gui.MenuItem();
        this.window2MenuItem.Title = "Window 2";
        this.window2MenuItem.Data = "window2MenuItem";
        this.window3MenuItem = new Terminal.Gui.MenuItem();
        this.window3MenuItem.Title = "Window 3";
        this.window3MenuItem.Data = "window3MenuItem";
        this.windowMenu.Children = new Terminal.Gui.MenuItem[] {
                this.window1MenuItem,
                this.window2MenuItem,
                this.window3MenuItem};
        this.menuBar.Menus = new Terminal.Gui.MenuBarItem[] {
                this.fileF9Menu,
                this.windowMenu};
        this.Add(this.menuBar);
    }
}
