Apple Privacy Manifest missing keys

This analyzer reported that isar_flutter_libs needs to add a privacy policy for these APIs:

I'm not sure if we need to add these keys; we only include them if they're explicitly necessary. Do you have any official links that definitively state whether we must include them, even when they're not needed?

Edit: According to official docs, it explicitly states: "if used" few times.
