DESCRIPTION:
    This sample demonstrates how to create an AI agent with SharePoint capabilities
    using the SharepointPreviewTool and synchronous Azure AI Projects client. The agent can search
    SharePoint content and provide responses with relevant information from SharePoint sites.

USAGE:
    python sample_agent_sharepoint.py

    Before running the sample:

    pip install "azure-ai-projects>=2.0.0" 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_MODEL_NAME - The deployment name of the AI model, as found under the "Name" column in
       the "Models + endpoints" tab in your Microsoft Foundry project.
    3) SHAREPOINT_PROJECT_CONNECTION_ID - The SharePoint project connection ID,
       as found in the "Connections" tab in your Microsoft Foundry project.
    4) SHAREPOINT_USER_INPUT - (Optional) The question to ask. If not set, you will be prompted.
