I would like to customize the selected tab of the MUI Tabs component. My styling choice is CSS modules. But I have difficulties applying the correct selector. I have also applied their CSS injection order so that I can customize the styles according to the docs.

I tried the following according to their documentation.
I have a class for my custom tab called .myTab.

.myTab.Mui-selected {
 color: red;
 border-radius: 50%;
}

then I apply the class to my Tab.

    <Tab
      className={classes.myTab}>
      {children}
    </Tab>

But I have no success so far.
