如何让我的slackbot在一个线程中回复，而不是使用Google App脚本回复整个频道

import requests
import json

def send_message(channel, thread_ts, text):
    url = "https://slack.com/api/chat.postMessage"
    headers = {
        "Content-Type": "application/json",
        "Authorization": "Bearer YOUR_SLACK_TOKEN"
    }
    data = {
        "channel": channel,
        "thread_ts": thread_ts,
        "text": text
    }
    response = requests.post(url, headers=headers, data=json.dumps(data))
    return response.json()

# 调用send_message函数发送回复消息
send_message("CHANNEL_ID", "THREAD_TS", "回复消息内容")
