admob and vanilla js for Android

I've been trying to add ADMOB to a test app for several days without success. Steps I've taken:

1. Add "@nativescript/google-mobile-ads": "^5.0.3"

2. In AndroidManifest.xml (./App_Resources/Android/src/main) add

<application..> ...
<meta-data  
android:name="com.google.android.gms.ads.APPLICATION_ID"   
android:value="ca-app-pub-3940256099942544~3347511713" />
...
</application>

3. in the app.js add

import { Application } from '@nativescript/core';
import { MobileAds } from '@nativescript/google-mobile-ads';

console.log("🔥 Inicializando Google Mobile Ads...");
MobileAds.init();

Application.run({ moduleName: 'main-page' });

Then "ns run android"

So far, I haven't been able to get it working.

Other data:
ns --version 8.9.2
windows 10 and vscode
Mi repo https://github.com/germandeburzaco/testMonetizarApp

首先，使用 issue 中显示的 app.js、AndroidManifest.xml 路径以及 @nativescript/google-mobile-ads 包版本，通过 ns run android 重现该设置。捕获缺失的构建或运行时错误，并将测试应用的配置与插件文档中的 Android 设置进行比较。当测试应用成功初始化 MobileAds 并显示预期的 AdMob 行为时，即表示完成。
