  The remove_reaction tool handler - an async function decorated with @mcp.tool() that removes reactions from WhatsApp messages. It takes parameters 'to', 'message_id', and optional 'sender', calls wa_client.remove_reaction(), logs the action, and returns a success status dictionary.

  async def remove_reaction(
      to: str,
      message_id: str,
      *,
      sender: Optional[str] = None,
  ) -> dict:
      """
      Remove a reaction from a message.
      
      Args:
          to: Phone number or WhatsApp ID
          message_id: ID of message to remove reaction from
          sender: Optional sender phone ID
      
      Returns:
          Dictionary with success status
      """
      try:
          result = wa_client.remove_reaction(
              to=to,
              message_id=message_id,
              sender=sender,
          )
          
          logger.info(f"Reaction removed from message {message_id}")
          result_data = str(result) if result else None
          return {"success": True, "result": result_data}
      except Exception as e:
          logger.error(f"Failed to remove reaction: {str(e)}")
          return {"success": False, "error": str(e)}
