Python3.x 无法使用Python slack 螺栓SDK读取在 slack 通道中收到的消息

我正在try 使用Slack Bolt PythonSDK阅读在一个私有的Slack频道上发布的消息.问题是，当我向此通道发布一些消息时，该方法根本不会被调用.

from typing import Optional
import slack_sdk
import os
import logging
from pathlib import Path
from dotenv import load_dotenv
from slack_bolt import App
from slack_bolt.adapter.socket_mode import SocketModeHandler

logging.basicConfig(level=logging.DEBUG)
env_path = Path('..') / '.env'
load_dotenv(dotenv_path=env_path)

SLACK_VERIFICATION_TOKEN = os.environ['SLACK_VERIFICATION_TOKEN']
SLACK_SIGNING_SECRET = os.environ['SLACK_SIGNING_SECRET']
SLACK_BOT_TOKEN = os.environ['SLACK_BOT_TOKEN']
SLACK_APP_TOKEN = os.environ['SLACK_APP_TOKEN']

app = App(token=SLACK_BOT_TOKEN, signing_secret=SLACK_SIGNING_SECRET)

@app.message("<Slack Channel Id>")  # Replace "your-channel-id" with your actual channel ID
 def handle_message(message, say):
     user = message["user"]
     text = message["text"]
     channel = message["channel"]

     # Do something with the received message
     print(f"Received message '{text}' from user {user} in channel {channel}")


if __name__ == "__main__":
    handler = SocketModeHandler(app, SLACK_APP_TOKEN)
    handler.start()

I have enabled subscriptions as well to events as message.channels event
