How to use the niceware.bytesToPassphrase function in niceware

return function * (client) {
    const data = []
    const buffer = new Buffer(2)
    for (let n = 0; n < total; n++) {
      buffer.writeUInt16BE(n)
      const string = niceware.bytesToPassphrase(buffer)[0]
      data.push({
        active: false,
        discarded: true,
        url: `https://www.${string}.com`
      })
    }
    yield client.waitForBrowserWindow()
    for (let datum of data) {
      yield client.newTab(datum, false, true) // isRestore
    }
  }
}
