                    <a href="{{ route('reviews') }}">
                        <span class="notification-counter-reviews">0</span> <!-- Notification counter -->
                        <span class="icon">
                            <ion-icon name="star-outline"></ion-icon>
                        </span>
                        <span class="title">Customer-Reviews</span>
                    </a>
