How to use the messaging-api-common.snakecaseKeys function in messaging-api-common

async _callAPI(
    path: string,
    body: Record = {}
  ): Promise | never> {
    try {
      const response = await this._axios.post(
        path,

        // we can't apply a deep snake_case transform here
        // because it accept only PascalCase for keyboard and rich media
        snakecaseKeys(body, { deep: false })
      );

      const { config, request } = response;

      const data = (camelcaseKeysDeep(
        response.data
      ) as any) as Types.ResponseData;

      if (data.status !== 0) {
        throw new AxiosError(`Viber API - ${data.statusMessage}`, {
          config,
          request,
          response,
        });
      }
