How to send AWSRequestsAuth via asyncio?

Question

Using the requests library, i can send requests to aws api gateway and pass an AWSRequestsAuth object. Behind the scenes this object inherites requests.auth.AuthBase.

I create an object like this:

auth = AWSRequestsAuth(
    aws_access_key=settings.aws_access_key,
    aws_secret_access_key=settings.aws_secret_access_key,
    aws_host=AWS_API_HOST,
    aws_region='eu-west-1',
    aws_service='execute-api'
)

then I send it with requests.post(url, data, auth=auth).

When using asyncio, I try:

    async def main():
        async with aiohttp.ClientSession() as session:
            async with session.post(
                 url,
                 data=data,
                 auth=auth
             ) as resp:
                 status = await resp.json()
                 print(status)

But I get the error TypeError: BasicAuth() tuple is required instead.

How can I send a request to aws gateway using auth, via asyncio?
