Slick

Hello everyone!) there is a slider

jQuery(document).ready(function($){
    $('.slider-for').slick({
      slidesToShow: 1,
      slidesToScroll: 1,
      arrows: false,
      fade: true,
      asNavFor: '.slider-nav'
    });
    $('.slider-nav').slick({
      slidesToShow: 4,
      slidesToScroll: 1,
      asNavFor: '.slider-for',
      dots: false,
      focusOnSelect: true,
      draggable: true,
      swipe: true,
      arrows: true,
      loop: true
    });
});

<div class="slide slider-nav">
                            <img src="/img/2015.png" alt="" class="img-slider-company">
                            <img src="/img/2015.png" alt="" class="img-slider-company">

                        </div>
                        <div class="slide slider-for">
                            <p class="paragraph-slider paragraph-slider__company">

                            </p>
                            <p class="paragraph-slider paragraph-slider__company">
                                4 ISO 9001:2015, ГАЗСЕРТ Новая модель крана «под задвижку»
                            </p>
                        </div>

When the number of slides is equal to slidesToShow, the arrows disappear. Plz tell me, how can I return them to turn the slides? Thank you in advance
