Can Maui View to Platform View be converted without creating a new project?

[vst-h]

I'm trying to develop an Input Method App and need to provide an InputMethodService. to override a method to return an Android.Views.View, I checked the documentation(native-embedding) and found that I need to create a new project to embed a View.

android doc creating-input-method

I don't want to create a project specifically for a View. Looking at the key code in the documentation, it should be necessary to create a MauiContext, here is my attempted code:

[Service]
public sealed class MyService: Android.InputMethodServices.InputMethodService {

    public override Android.Views.View? OnCreateInputView() {
        Microsoft.Maui.Controls.View mauiView = null!;

        var app = MauiApp.CreateBuilder().UseMauiEmbedding<WhereApp>().Build();
        var context = new MauiContext(app.Services);

        Android.Views.View aView = mauiView.ToPlatform(context);
        return aView;
    }
}

• I'm a first time developer of a mobile app and I feel that the input method is not an app embedded in a View, do I need to add UseMauiEmbedding?
• My View is created by an Android Service call, the App doesn't have a main entry point to start, what should I write for the generic WhereApp?

Some development experience would be greatly appreciated!

I looked up the UseMauiEmbedding source code and it actually calls UseMauiApp directly. I tried the following code and it converts and brings up the interface fine:

        var app = MauiApp.CreateBuilder().UseMauiApp<Microsoft.Maui.Controls.Application>().Build();
        var context = new MauiContext(app.Services, this.ApplicationContext ?? this.BaseContext!);

        var aView = mauiView.ToPlatform(context);
