• After removing the buttonOuter prop, these buttons will no longer render a .btn-outer wrapper. ProgressBar.scss still contains .progress-bar .btn-outer { ... } overrides, so verify the desired padding/click-target styling still applies and consider removing or updating the now-unused .btn-outer rule to avoid dead CSS.

        <Button
          className={"btn--secondary btn--small"}
          onClickHandler={goToPreviousStep}
          ButtonIcon={ChevronLeft}
          disabled={currentStepPosition === 0}
          title={t("instructionsPanel.previousStep")}
        />
