FILE: sample_conversation_pii_with_no_mask_policy_async.py

DESCRIPTION:
    This sample demonstrates how to run a PII detection action over a conversation
    using the `NoMaskPolicyType`, which detects PII but does NOT redact it
    (the original text is returned).

USAGE:
    python sample_conversation_pii_with_no_mask_policy_async.py

REQUIRED ENV VARS (for AAD / DefaultAzureCredential):
    AZURE_CONVERSATIONS_ENDPOINT
    AZURE_CLIENT_ID
    AZURE_TENANT_ID
    AZURE_CLIENT_SECRET

NOTE:
    If you want to use AzureKeyCredential instead, set:
      - AZURE_CONVERSATIONS_ENDPOINT
      - AZURE_CONVERSATIONS_KEY
