     forwardMessage,
     pinMessage,
     starMessage,
     markMessageRead,

   } = useMessageMutations()

3. Call the functions:

   await updateMessage(messageId, { content: 'New content' })
   await pinMessage(messageId, channelId)
   await starMessage(messageId)

4. See documentation:

   • Quick reference: docs/advanced-messaging-quick-reference.md
