Add the following helper method in Util

    private static Component findComponent(final Container container,
                                           final Predicate<Component> predicate) {
        for (Component child : container.getComponents()) {
            if (predicate.test(child)) {
                return child;
            }
            if (child instanceof Container cont && cont.getComponentCount() > 0) {
                Component result = findComponent(cont, predicate);
                if (result != null) {
                    return result;
                }
            }
        }
        return null;
    }
