How to launch an application without a launch icon by scanning an NFC tag?

I want to run the application by scanning the NFC tag containing the Android Application Record . However, there should not be a launch icon for this application, so I cannot use it CATEGORY_LAUNCHER.

My problem is that if I comment out a line CATEGORY_LAUNCHERin the manifest, the application no longer starts (the search is done on Google Play):

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="app.my">

    <application android:label="@string/app_name">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <!--<category android:name="android.intent.category.LAUNCHER" />-->
            </intent-filter>
        </activity>
    </application>
</manifest>

I also tried adding the following intent filter, but no luck:

<intent-filter>
    <action android:name="android.nfc.action.NDEF_DISCOVERED" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="text/plain" />
</intent-filter>

What should I do to make it work? Should I add code in MainActivityto handle the intent NDEF_DISCOVERED?
