How to use the netlify/src/addons.updateAddon function in netlify

const codeDiff = diffValues(currentConfig, newConfig)
  if (!codeDiff) {
    logger('No changes, exiting early')
    return false
  }
  logger()
  const msg = `Updating ${addonName} add-on config values...`
  logger(`${chalk.white.bold(msg)}`)
  logger()
  logger(`${codeDiff}\n`)
  logger()

  let updateAddonResponse
  try {
    // TODO update updateAddon to https://open-api.netlify.com/#/default/updateServiceInstance
    updateAddonResponse = await updateAddon(settings, accessToken)
  } catch (e) {
    error(e.message)
  }
  if (updateAddonResponse.code === 404) {
    logger(`No add-on "${addonName}" found. Please double check your add-on name and try again`)
    return false
  }
  logger(`Add-on "${addonName}" successfully updated`)
  return updateAddonResponse
}

// Parse flags
    const rawFlags = parseRawFlags(raw)

    // TODO diff rawFlags and currentConfig and dont make API call if equal

    // Merge current config with new values passed in
    const newConfigValue = mergewith(currentConfig, rawFlags)

    const settings = {
      siteId: siteId,
      instanceId: currentAddon.id,
      addon: addonName,
      config: newConfigValue
    }

    const updateAddonResponse = await updateAddon(settings, accessToken)
    // this.log('addonResponse', updateAddonResponse)

    if (updateAddonResponse.code === 404) {
      this.log(`No addon "${addonName}" found. Please double check your addon name and try again`)
      return false
    }
    this.log(`Addon "${addonName}" updated`)
  }
