ios – Apple Watch not receiving notifications from Firestore Cloud Messaging Notification

I exploit firestore cloud messaging (from a cloud operate) to set off notifications to apple units:

const payload = {
    notification: {
      title, 
      physique,
      sound: "default",
    },
    knowledge: payloadBody
  };

This works as anticipated and would not have any points, I can pull the payload from the ios code, the notification shows and so forth. Nonetheless, apple watches do not obtain the notification. I’ve checked all settings, tried a number of units, and so forth.

Do we’ve to retailer fcm tokens for watches separatley? Or what must be completed to attain notifications on watches? Or ought to this work as default behaviour and a bug ticket be raised?
