"directories" in the root is deprecated, please specify in the "build"

Hi, I’m a little new to electron and am currently trying electron builder. I can’t seem to run the programmatic usage of electron-builder or at least I don’t understand the documents on how. Here is my current code:

"use strict"

const builder = require("electron-builder")

const Platform = builder.Platform


builder.build({
    targets: Platform.WINDOWS.createTarget('msi'),
    config: {
    }
})
  .then(() => {
    console.log('OK')
  })
  .catch((error) => {
    console.log(error)
  })

How can I use it programmatically? Thank you.
