How to make it possible to import only one element from a react storybook and not pull the library every time?

Question

React

What would be instead of this
import { Checkbox } from 'mystory' // 4.56 MB

import Checkbox from 'mystory/Checkbox'  // 27.56 kB

Where is it written about this in the documentation?

Answer 1

but from webpack, surely the js bundle comes out the same size?
that is, during assembly, it pulls only the necessary export from the library
