What is the best way of handling conditional styles together with this plugin?

First off, thanks you for this amazing library. It solves a huge problem and really cleans up my code. I know it's a matter of opinion but I'm curious what the most idiomatic / readable / cleanest way to handle conditional styles together with this plugin? Here's my current approach with a functional component. Does anyone have any other patterns?

```
import React from 'react';
import './Modal.module.scss';

const Modal = (props) => {

const animateModal = () => {
if (props.show === true) {
return('modal animate-in');
}

return('modal animate-out');
}

return (

export default Modal;
```
