How should I use this within RabbitSubscribe method?

[Tomtom]

@Injectable()
export class MqService {
  constructor(
    private readonly amqpConnection: AmqpConnection,
  ) {
    this.handleMessage = this.handleMessage.bind(this);
  }

  public async sendDelayedMessage(data: string, delay: number) {
    await this.amqpConnection.publish('delayed_exchange', 'delete_domain', { data }, { headers: { 'x-delay': delay } });
  }

  @RabbitSubscribe({
    exchange: 'delayed_exchange',
    routingKey: 'delete_domain',
    queue: 'delayed_queue',
  })
  public async handleMessage(message: { data: string }) { 
    console.log(this); // ==> {}
  }
}

How should I use this within handleMessage?
