`transform` seem to be exported incorrectly

[ShineKidd]

Node: v14.17.5

const { transform } = require('unplugin-vue2-script-setup')
console.log(transform) // print undefined

I configure my jest followed the documentation, not work

module.exports = {
  transform: {
    '.*\\.(vue)$': 'unplugin-vue2-script-setup/jest',
  },
}
