How to set up the webpack CommonsChunkPlugin properly for a project?

Question

JavaScript

I'm trying to set up a react project to connect scripts depending on the user's role.
there are production build settings

entry: [
    './src/index'
  ],
  output: {
    path: path.join(__dirname, 'dist'),
    filename: 'bundle.js',
    publicPath: '/static/'
  },

the project has src/admin/users.js which is not an entry point, but connects to one of the buttons and is accordingly assembled into bundle.js
It is not possible to embed this piece from the documentation correctly

new CommonsChunkPlugin({
            name: "admin-commons",
            chunks: ["adminPageA", "adminPageB"]
        }),
        new CommonsChunkPlugin({
            name: "commons",
            chunks: ["pageA", "pageB", "admin-commons.js"],
            minChunks: 2
        })

how to configure breakdown without an entry point (or do you need to make a separate application in the project itself)?
