How to use icons in freeSet in r2.0.1
I have installed coreui/icons r2.0.1 via npm, and in src/index.js:
React.icons = icons

While, I try to use cli-cart as follow:
`<CIcon content="cil-cart" />`

The console log tells me:
CIcon component: icon name 'cil-cart' does not exist in React.icons object. To use icons by `name` prop you need to make them available globally by adding them to React.icons object. CIcon component docs: https://coreui.io/react/docs/components/CIcon 

I follow the steps in:
https://github.com/coreui/coreui-react/issues/177
https://stackoverflow.com/questions/62840344/coreui-icon-doesnt-appear-in-my-react-js-app

But it doesn't show any icons? Do I miss something?

Thanks.
