FILE: router_worker_crud_ops_async.py
DESCRIPTION:
    These samples demonstrates how to create Workers used in ACS JobRouter.
    You need a valid connection string to an Azure Communication Service to execute the sample

USAGE:
    python router_worker_crud_ops_async.py
    Set the environment variables with your own values before running the sample:
    1) AZURE_COMMUNICATION_SERVICE_ENDPOINT - Communication Service endpoint url
