    // We demonstrated how to get an access token for your Azure Key Vault
    // in this example: Azure Key Vault Get OAuth2 Access Token using Client Credentials

    // However.. starting in Chilkat v9.5.0.96, instead of directly providing Chilkat with the OAuth2 access token,
    // you can instead provide the means for Chilkat to automatically get the OAuth2 access token,
    // and in addition, Chilkat will automatically re-fetch a new OAuth2 access token as needed, such as shortly 
    // prior to or after expiration.

    // You do this by setting the AuthToken property to a JSON string that contains the required information.
