How to use the @liquality/ethereum-utils.formatEthResponse function in @liquality/ethereum-utils

_parseResponse (response) {
    const data = super._parseResponse(response)

    return formatEthResponse(data)
  }

if (error) {
            reject(new WalletError(error.toString(), error))
            return
          }

          if (!data) {
            reject(new WalletError('Metamask response was empty'))
            return
          }

          if (typeof data.result === 'undefined') {
            reject(new WalletError('Metamask response was empty'))
            return
          }

          const formattedResult = formatEthResponse(data.result)

          resolve(formattedResult)
        })
    })
