DESCRIPTION:
    This sample demonstrates how to perform CRUD operations on agent Sessions
    using the synchronous AIProjectClient.

    Sessions only work with Hosted Agents.

    Sessions are currently a preview feature. In the Python SDK, you access
    these operations via `project_client.beta.agents`.

USAGE:
    python sample_sessions_files_upload_download.py

    Before running the sample:

    pip install "azure-ai-projects>=2.1.0" python-dotenv

    Set these environment variables with your own values:
    1) FOUNDRY_PROJECT_ENDPOINT - The Azure AI Project endpoint, as found in the Overview
       page of your Microsoft Foundry portal.
    2) FOUNDRY_AGENT_CONTAINER_IMAGE - The Hosted Agent container image in the format '<registry>/<repository>[:<tag>|@<digest>]'

    You can build and push an example image from
    `samples/hosted_agents/assets/responses-echo-agent` and use that image value
    for `FOUNDRY_AGENT_CONTAINER_IMAGE`.
