CSS class names autocompletion in Javascript variables Follow

Is there any way to autocomplete css class names inside a javascript variable.

Usually everyone uses CSS class names directly inside html/jsx. And Jetbrains IDEs are smart to suggest CSS classes by autocompletion.

I want a way to suggest class names inside Javascript variables too. Currently it goes without any suggestion inside variables.

Is there a way to customize IDE to suggest CSS classes inside JS variables i.e. btnClasses.
