    // Analytics configuration options
  },

  // Session Replay options
  sessionReplay: {
    // Session Replay configuration options
  },

  // Experiment options
  experiment: {
    // Experiment configuration options

  // Guides and Surveys options
  engagement: {
    // Guides and Surveys configuration options
  },
});
```

### 3. Access SDK Features

The Unified SDK provides access to all Amplitude features through a single interface:

```typescript
import {
  track,
  identify,
  experiment,
  sessionReplay
} from '@amplitude/unified';

// Track events
track('Button Clicked', { buttonName: 'Sign Up' });

// Identify users
identify(new Identify().set('userType', 'premium'));

// Access Experiment features
const variant = await experiment.fetch('experiment-key');

// Access Session Replay features
sessionReplay.flush();

// Access Guides and Surveys features via engagement global
const activeGuidesAndSurveys = await engagement.gs.list();
```
