无法通过API获取公众号聊天记录
https://developers.weixin.qq.com/doc/offiaccount/Customer_Service/Obtain_chat_transcript.html 使用接口请求，一直返回空数据，我的AppID是wx4944b0999bb91896 接口地址：
url = f"https://api.weixin.qq.com/customservice/msgrecord/getmsglist?access_token={access_token}"
请求数据：
data = {
"starttime" : 1705407962,
"endtime" : 1705490762,
"msgid" : 1,
"number" : 10000
}
response = requests.post(url, json=data).text
响应内容：
