import { Controller, OnCommand, Pin } from 'nestgram';
import { AppService } from './app.service';

@Controller()
export class AppController {
  constructor(private readonly appService: AppService) {}

  @OnCommand('pin_me')
  pinMe() {
    return new Pin();
  }
}
```

{% endcode %}

## Unpin message

import { AppService } from './app.service';

@Controller()
export class AppController {
