Android：点击本地通知无法打开应用

Question

我有下面的代码正在运行，并显示本地通知！

MainActivity.java

//
Intent intent = new Intent(GlobalApplication.getAppContext(), AlarmReceiver.class);
intent.setAction("android.intent.action.MAIN");
intent.putExtra("NotificationText", "some text");
PendingIntent pendingIntent = PendingIntent.getBroadcast(GlobalApplication.getAppContext(), 4, intent, PendingIntent.FLAG_UPDATE_CURRENT);
sendBroadcast(intent);

// 
NotificationCompat.Builder builder = new NotificationCompat.Builder(context, "CHANNEL_ID")
        .setSmallIcon(R.drawable.ic_launcher_background)
        .setContentTitle("Please keep app running")
        .setContentText("This is KILLER notification brother")
        .setPriority(NotificationCompat.PRIORITY_HIGH);
Log.e(TAG, "Notified AOS to post notification");
notificationManager.notify(123, builder.build());

AndroidManifest.xml

    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

点击本地通知不会打开应用程序。 这不是推送通知，因此我可以添加一些操作。

点击本地通知后，我如何才能打开应用？
