How To Disable "Restore Down" In .NET MAUI Blazor Component App

I have created one .NET MAUI Blazor Component App.

I want to restrict user to not to restore down the window. Simply, I want to disable below button in Windows as well as MAC Catalyst.

You can use the code below in the MauiProgram.cs. It can disable the maximize button on the windows platform and make the window maximize.

#if WINDOWS
        builder.ConfigureLifecycleEvents(events =>
        {
            // Make sure to add "using Microsoft.Maui.LifecycleEvents;" in the top of the file
            events.AddWindows(windowsLifecycleBuilder =>
            {
                windowsLifecycleBuilder.OnWindowCreated(window =>
                {
                    window.ExtendsContentIntoTitleBar = false;
                    var handle = WinRT.Interop.WindowNative.GetWindowHandle(window);
                    var id = Microsoft.UI.Win32Interop.GetWindowIdFromWindow(handle);
                    var appWindow = Microsoft.UI.Windowing.AppWindow.GetFromWindowId(id);
                    switch (appWindow.Presenter)
                    {
                        case Microsoft.UI.Windowing.OverlappedPresenter overlappedPresenter:
                            overlappedPresenter.Maximize();
                            overlappedPresenter.IsMaximizable = false;
                            break;
                    }
                });
            });
        });
#endif
