Need to make a Firebase Game Loop Test

I need to make a test on firebase. Currently I get this error:

The application does not include a game loop intent filter, or the intent filter is not formatted correctly.

Here is a picture:

Currently I am adding to manifest using UPL like this:

<?xml version="1.0" encoding="utf-8"?>
<root xmlns:android="http://schemas.android.com/apk/res/android">

  <androidManifestUpdates>
    <insert>
      <activity android:name=".MyActivity">
        <intent-filter>
          <action android:name="com.google.intent.action.TEST_LOOP"/>
          <category android:name="android.intent.category.DEFAULT"/>
          <data android:mimeType="application/javascript"/>
        </intent-filter>
      </activity>
    </insert>
  </androidManifestUpdates>

</root>

But it is not getting added to the main xml, I don’t know why.
Can someone help me resolve this issue?
