How to use the @material/select.cssClasses.FOCUSED function in @material/select

const doWork = () => {
          const value = f.getValue();

          // This is the line we have to override to work with placeholders
          // we need to consider haveing a placeholder as a valid value
          const optionHasValue = !!getProps().placeholder || value.length > 0;

          if (adapter.hasLabel()) {
            f.notchOutline(optionHasValue);

            if (!adapter.hasClass(cssClasses.FOCUSED)) {
              adapter.floatLabel(optionHasValue);
            }
          }
        };
