How to inherit the properties from a class when using CSS Modules?

Question

I am making a collapsible sidebar, for that I have 2 classes:

.sidebar {
    background-color: #f5fafa;
    width: 5vw;
    height: 100vh;
    margin: 0;
    display: flex;
    flex-direction: column;
    align-items: center;
}

.sidebar__expanded {
    background-color: #f5fafa;
    width: 10vw;
    height: 100vh;
    margin: 0;
    display: flex;
    flex-direction: column;
    align-items: center;
}

As you can see, every property is same except the width of the two, so I want to inherit the common properties from the .sidebar . How to do that when using CSS Modules ? I have tried using the inherit and the composes keyword but none of them seem to work , the terminal says property value expected in both. How to do that?

Thank you so much in advance!
