We are using PWA venia theme 2.4.5. We are trying to add a button below ADD TO WISHLIST in PDP Page

We tried the below code . but we are not seeing any button.

{
  isMobile && (
    <div className={classes.cartActionButton}>
      <div className="px-3 h-[46px] m-auto w-full">
        {cartActionContent}
        <Suspense fallback={null}>
          <WishlistButton {...wishlistButtonProps} style={{ color: "red" }} />
        </Suspense>
        <button type="button">Custom button</button>
      </div>
    </div>
  );
}
