如何在discord.py中使用gmail API每分钟在聊天中以单独消息的形式发送最近10封未读的电子邮件？

pip install discord.py google-api-python-client google-auth-httplib2 google-auth-oauthlib

import discord
import os
import pickle
import base64

import google.auth
from google_auth_oauthlib.flow import InstalledAppFlow

SCOPES = ['https://www.googleapis.com/auth/gmail.readonly']
TOKEN_PICKLE = 'token.pickle'
EMAIL_COUNT = 10

def get_gmail_service():
    creds = None
    if os.path.exists(TOKEN_PICKLE):
        with open(TOKEN_PICKLE, 'rb') as token:
            creds = pickle.load(token)
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file('credentials.json', SCOPES)
            creds = flow.run_local_server(port=0)
        with open(TOKEN_PICKLE, 'wb') as token:
            pickle.dump(creds, token)
    service = build('gmail', 'v1', credentials=creds)
    return service

def get_unread_emails(service):
    results = service.users().messages().list(userId='me', labelIds=['INBOX', 'UNREAD'], maxResults=EMAIL_COUNT).execute()
    messages = results.get('messages', [])
    return messages

def get_email_content(service, message_id):
    message = service.users().messages().get(userId='me', id=message_id).execute()
    return message['snippet']

@client.event
async def on_ready():
    print('Bot is ready.')
    service = get_gmail_service()
    while True:
        messages = get_unread_emails(service)
        for message in messages:
            content = get_email_content(service, message['id'])
            await client.send_message(discord.Object(id='YOUR_CHANNEL_ID'), content)
        await asyncio.sleep(60)  # 每分钟循环一次

client.run('YOUR_DISCORD_BOT_TOKEN')
