Message_send webhook doesn't contain multiple files

Sendbird Dashboard
1
  1. Use the UI React Kit
  2. Set isMultipleFilesMessageEnabled={true} on a group channel
  3. Upload multiple images at once (using the UI React Kit, no modifications).
  4. Configure Chat Webhook with message_send event.
  5. The event payload contains data only on 1 of the uploaded files, not all of them.

This makes a webhook an unreliable source of user events.

Have I configured something wrong?
Is there any way to receive the list of uploaded files from the webhook event?
files does exist when we fetch the message via API, but this adds huge latency, and again, this makes a webhook an unreliable source of user events.

Thanks
