Large bundle size. Is there a way to reduce it?

Hi!

I’ve started working with CoreUI (@coreui/react 3.3.3 and @coreui/coreui 3.3.0) library and noticed, that it loads large bundles.
Before that I used @coreui version 2 and there wasn’t such problem. After upgrade amount of Mbs to load increased 3 times.

For example: https://monosnap.com/file/V1dnroYbZeBsqZbx3yPdgB4OyVngRP

The issue exists even if I use the library for clean create-react-app installation and import any component from @coreui/react:

import React from 'react';
import { CButton } from '@coreui/react'; 

const App = () => (
  <div>Test</div>
);

export default App;

Could you please tell me if there is a way to reduce the bundle size?
