Reuse http session to improve performance using client as a context manager:
py
import asyncio
import aiohttp

from okta.client import Client as OktaClient


async def main():
async with OktaClient() as client:
perform all queries within same session
users, okta_resp, err = await client.list_users()
user, okta_resp, err = await client.get_user(users[0].id)


loop = asyncio.get_event_loop()
loop.run_until_complete(main())
