redis_options in socketio.AsyncRedisManager don't seem to work

[ghost]

Heroku is forcing an upgrade to redis 7 which requires ssl.
I have the following code that I've added ssl to

import socketio
from engineio.payload import Payload
from os import environ

REDIS_URL = environ.get("REDIS_URL") or "redis://"
mgr = socketio.AsyncRedisManager(REDIS_URL, redis_options={"ssl_cert_reqs": None})

sio = socketio.AsyncServer(
    cors_allowed_origins=['https://mywebsite.com'],
    client_manager=mgr,
    async_mode="asgi",
    ping_timeout=5,
    ping_interval=25,
    engineio_logger=False,
    logger=False,
)

according to the docs
redis_options – additional keyword arguments to be passed to Redis.from_url().

I'm expecting this to work with redis_options specified above but when I run it I receive

__init__() got an unexpected keyword argument 'ssl_cert_reqs'

My full traceback is

Am I doing something wrong or are the docs incorrect?

I was using "redis://" instead of "rediss://"
