Current behavior

When I use arrayUnion in setDocument on the web this is what I get

The result is perfect and I tested extensively and I'm happy with the result.

But when used on iOS this is the result

_methodName & wu are added and I'm not sure why...

My code is fairly simple, maybe because arrayUnion is imported from firebase/firestore

import { FirebaseFirestore } from '@capacitor-firebase/firestore';
import { arrayUnion, Timestamp } from 'firebase/firestore';

const messages = userId
  ? arrayUnion({
      id: nanoid(8),
      text,
      timestamp: Timestamp.now(),
      userId
    })
  : [];

await FirebaseFirestore.setDocument({
  reference: `trips/${tripId}/chats/${stopId}`,
  data: { messages },
  merge: true
});

Expected behavior

I'd would expect the web & native result to match
