DESCRIPTION:
    This sample demonstrates how to use agent operations with interation in streaming from
    the Azure Agents service using a asynchronous client.

USAGE:
    python sample_agents_stream_iteration_async.py

    Before running the sample:

    pip install azure-ai-agents azure-identity aiohttp

    Set these environment variables with your own values:
    1) PROJECT_ENDPOINT - The Azure AI Project endpoint, as found in the Overview 
                          page of your Azure AI Foundry portal.
    2) MODEL_DEPLOYMENT_NAME - The deployment name of the AI model.
