Unable to connect to Azure Cosmos DB using Corporate Proxy

I am trying to use Azure Cosmos DB as my document database using Python SDK library. And it seems that I unable to connect to cosmos DB using corporate proxy if I pass the proxy information using "ProxyConfiguration" or "ConnectionPolicy". To me its seems like there is an issue with the python SDK. But it I set the proxy at OS level then I am able to establish the connection Azure Cosmos DB but my other API call also go via this proxy and stopped working. Below is my code. Kindly help me to resolve the issue.

import os
from azure.cosmos import CosmosClient, exceptions, PartitionKey, ProxyConfiguration
from azure.cosmos.documents import ConnectionPolicy

URL = "https://company.documents.azure.com:443/"
KEY = "someKey"

# Solution - 1
corp_proxy = ProxyConfiguration()
corp_proxy.Host = 'companyProxyHostname.nic'
corp_proxy.Port = 9090
client = CosmosClient(URL, credential=KEY, proxy_config=corp_proxy)

# Solution - 2
connection_policy = ConnectionPolicy()
connection_policy.ProxyConfiguration = documents.ProxyConfiguration()
connection_policy.ProxyConfiguration.Host = 'companyProxyHostname.nic'
connection_policy.ProxyConfiguration.Port = 9090
client = CosmosClient(URL, credential=KEY, connection_policy=connection_policy)

The below solution works well

import os
from azure.cosmos import CosmosClient, exceptions, PartitionKey, ProxyConfiguration

os.environ['http_proxy'] = 'http://companyProxyHostname.nic:9090'
os.environ['HTTP_PROXY'] = 'http://companyProxyHostname.nic:9090'
os.environ['https_proxy'] = 'http://companyProxyHostname.nic:9090'
os.environ['HTTPS_PROXY'] = 'http://companyProxyHostname.nic:9090'

client = CosmosClient(URL, credential=KEY)

    Issue: You are facing issues connecting to Azure Cosmos DB using a corporate proxy. you have tried passing the proxy information using "ProxyConfiguration" or "ConnectionPolicy" but unable to establish a connection. However, setting the proxy at the OS level works, but it affects other API calls as well.

    Solution: As you mentioned you found that both ProxyConfiguration() and ConnectionPolicy() is not configured correctly, and you were able to resolve the issue by passing the proxies in *kwarg

    client = CosmosClient(URL, credential=KEY, proxies={"https":"hostname:port"})
