DESCRIPTION:
    This sample demonstrates how to use the File Search Tool with streaming responses using the async client.
    It combines file search capabilities with response streaming to provide real-time
    search results from uploaded documents.

USAGE:
    python sample_agent_file_search_in_stream_async.py

    Before running the sample:

    pip install "azure-ai-projects>=2.0.0b1" python-dotenv aiohttp

    Set these environment variables with your own values:
    1) AZURE_AI_PROJECT_ENDPOINT - The Azure AI Project endpoint, as found in the Overview
       page of your Microsoft Foundry portal.
    2) AZURE_AI_MODEL_DEPLOYMENT_NAME - The deployment name of the AI model, as found under the "Name" column in
       the "Models + endpoints" tab in your Microsoft Foundry project.
