  clevertapLogger.init({ accountId: 'YOUR_ACCOUNT_ID', region: 'YOUR_ACCOUNT_REGION' });
  
  const app = express();
  
  app.use((req, res, next) => {
    clevertapLogger.info(\`Incoming request: \${req.method} \${req.url}\`);
    next();
  });
  
  app.get('/', (req, res) => {
    clevertapLogger.debug('Handling root route');
    res.send('Hello World');
