Simplified SharePoint HTTP Client

// In a real application, retrieve these securely, e.g., from environment variables or a config service.
// This example uses dummy values for demonstration. For specific auth types and options,
// refer to the `node-sp-auth` documentation (https://github.com/s-KaiNet/node-sp-auth#params).

  // Example for SharePoint Online App-Only via Client ID/Secret:
  // clientId: process.env.SP_CLIENT_ID ?? 'your-client-id',
  // clientSecret: process.env.SP_CLIENT_SECRET ?? 'your-client-secret',

  // Example for SharePoint Online with ADFS/Forms auth via username/password:
  username: process.env.SP_USERNAME ?? 'user@yourtenant.onmicrosoft.com',
  password: process.env.SP_PASSWORD ?? 'YourSecurePassword123!',
