Is it possible to use a custom port in app links?

Question

I tried to add a port to my app links, but I can't get it to work. Nothing is mentionned in the doc: https://developer.android.com/training/app-links/verify-android-applinks

But at same time AndroidStudio autocomplete the android:port attribute and I also succeeded to validate my app links with this Google tool : https://developers.google.com/digital-asset-links/tools/generator?hl=fr

      <intent-filter android:autoVerify="true">
        <action android:name="android.intent.action.VIEW"/>
        <category android:name="android.intent.category.DEFAULT"/>
        <category android:name="android.intent.category.BROWSABLE"/>
        <data android:host="my-domain.com" android:port="203" android:scheme="https" />
      </intent-filter>
