Args: channel: Channel ID where the message exists timestamp: Timestamp of the message emoji_name: Name of the emoji (without colons) """ try: client = SlackClient() result = await client.remove_reaction(channel, timestamp, emoji_name) return json.dumps(result, indent=2) except Exception as e: return json.dumps({"error": str(e)}, indent=2)
