    throw new Error('Method not implemented.');
  }
  config(config?: LogAdapterConfig | undefined): LogAdapter {
    throw new Error('Method not implemented.');
  }
  print(priority: LogLevel, context: string, message: T, trace?: any): void {
    throw new Error('Method not implemented.');
  }
}

// customize custom format strategy for `CustomAdapter`
export class CustomFormatStrategy<T> implements FormatStrategy<T> {
  print(priority: LogLevel, context: string, message: T, trace?: any): void {
    throw new Error('Method not implemented.');
  }
}

// create new logger
const logger = createLogger({
  logLevel: LogLevel.Warn,
  adapter: new SentryAdapter({
    formatStrategy: new SentryFormatStrategy(),
  }),
});

// attach new adapter
logger.addLogAdapter(
  new SentryAdapter({
