How to use the @seagull/libraries.getAppName function in @seagull/libraries

constructor(params: WriteLogRequest) {
    super()
    const events = mapLogToEvent(params.log, params.logLevel)
    this.params = {
      logEvents: events,
      logGroupName: `/${getAppName()}/data-log`,
      logStreamName: createStreamName(params.logStreamName),
    }
  }

constructor(params: GetLogsRequest) {
    super()
    const groupName = {
      logGroupName: params.logGroupName || `/${getAppName()}/data-log`,
    }
    this.params = { ...params, ...groupName }
  }

constructor(params: WriteLogsRequest) {
    super()
    const events = mapLogToEvents(params.logs, params.logLevel)
    this.params = {
      logEvents: events,
      logGroupName: `/${getAppName()}/data-log`,
      logStreamName: createStreamName(params.logStreamName),
    }
  }

constructor(params: AddLogRequest) {
    super()
    const events = mapLogToEvent(params.log, params.logLevel)
    this.params = {
      logEvents: events,
      logGroupName: `/${getAppName()}/data-log`,
      logStreamName: params.logStreamName,
      sequenceToken: params.sequenceToken,
    }
  }

constructor(logStreamName: string) {
    super()
    this.logGroupName = `/${getAppName()}/data-log`
    this.logStreamName = createStreamName(logStreamName)
  }
