// Application permissions - daemon/service app
var tenantId = "YOUR_TENANT_ID";
var clientId = "YOUR_CLIENT_ID";
var clientSecret = "YOUR_CLIENT_SECRET";

var credential = new ClientSecretCredential(tenantId, clientId, clientSecret);
var graphClient = new GraphServiceClient(credential);

// Example: GET /users/{user-id}
var users = await graphClient.Users.GetAsync();
foreach (var user in users?.Value ?? [])
{
    Console.WriteLine($"User: {user.DisplayName}");

const pca = new PublicClientApplication(msalConfig);
await pca.initialize();



// Application: Use client credentials (Node.js backend only)
// npm install @azure/identity @microsoft/microsoft-graph-client
import { ClientSecretCredential } from "@azure/identity";
import { TokenCredentialAuthenticationProvider } from 
    "@microsoft/microsoft-graph-client/authProviders/azureTokenCredentials";
