How to use css modifiers with css modules?

Question

JavaScript

There is a Button component (base), which I expand with the SubmitButton component, passing styles as props, and then I want to use this css module.
Question, how to use two css modules in className? Example:

<a href={'#'} className={Button.someStyle   SubmitButton.someStyle}>
 Отправить
</a>

Answer 1

Styles in props? Seriously?
