How to use the @electron/get.downloadArtifact function in @electron/get

const path = require('path')
const extract = require('extract-zip')
const { downloadArtifact } = require('@electron/get')

if (process.env.ELECTRON_SKIP_BINARY_DOWNLOAD) {
  process.exit(0)
}

const platformPath = getPlatformPath()

if (isInstalled()) {
  process.exit(0)
}

// downloads if not cached
downloadArtifact({
  version,
  artifactName: 'electron',
  mirrorOptions: { mirror: "https://github.com/castlabs/electron-releases/releases/download/" },
  force: process.env.force_no_cache === 'true',
  cacheRoot: process.env.electron_config_cache,
  platform: process.env.npm_config_platform || process.platform,
  arch: process.env.npm_config_arch || process.arch
}).then(extractFile).catch(err => {
  console.error(err.stack)
  process.exit(1)
})

function isInstalled () {
  try {
    if (fs.readFileSync(path.join(__dirname, 'dist', 'version'), 'utf-8').replace(/^v/, '') !== version) {
      return false

}

if (process.env.ELECTRON_SKIP_BINARY_DOWNLOAD) {
  process.exit(0)
}

const platformPath = getPlatformPath()

const electronPath = process.env.ELECTRON_OVERRIDE_DIST_PATH || path.join(__dirname, 'dist', platformPath)

if (installedVersion === version && fs.existsSync(electronPath)) {
  process.exit(0)
}

// downloads if not cached
