我有这个代码在python中工作，我需要把它转换成nodejs，但是我找不到任何等价于sasl_oauth_token_provider这个属性的代码。

import time
from kafka import *
from kafka.errors import KafkaTimeoutError
from oauthlib.oauth2 import BackendApplicationClient
from requests_oauthlib import OAuth2Session

producer = KafkaProducer(bootstrap_servers='xxx',
                         security_protocol='SASL_SSL',
                         ssl_check_hostname=True,
                         sasl_mechanism='OAUTHBEARER',
                         sasl_plain_username=client_id,
                         sasl_plain_password=client_secret,
                         sasl_oauth_token_provider="xxx",
                         )

对于nodej，我使用node-rdkafka库，我得到的最接近的等效代码是-

const kafka = require('node-rdkafka');

const producer = new kafka.Producer({
'metadata.broker.list': 'xxx',
'security.protocol': 'sasl_ssl',
'sasl.mechanism': 'OAUTHBEARER',
'sasl.username': 'xxx',
'sasl.password': 'xxx',
});
