删除电报机器人写的所有消息？

Question

我失去了我的群组管理员，所以我想删除群组中的所有消息或者我可以给我的帐户管理员吗？

导入电报

# bot token
TOKEN = "+++++++++++"

# chat_id of the chat whose messages are to be deleted
chat_id = "@+++++++++++"

# create a bot instance
bot = telegram.Bot(token=TOKEN)

# get the list of messages in the chat
messages = bot.get_chat(chat_id).get('message', [])

# delete each message
for message in messages:
    bot.delete_message(chat_id=chat_id, message_id=message['message_id'])

  File "C:\Users\serdd\OneDrive\deo\main.py", line 13, in <module>
    messages = bot.get_chat(chat_id).get('message', [])
