Prestige theme "add to cart" in collection with lateral menu

Store Design

Hi,

I realized on the site: https://helssyhair.com/

Preview for help me : https://lrep2n8d956oynuj-50154504344.shopifypreview.com

An add to basket button on the collections the button works correctly and the menu is displayed laterally on android on the other hand on Ios when I click on add to basket the addition to the basket is carried out but there is a redirection to the basket page

document.querySelectorAll("button.ad_to_cart_coll").forEach((item,index)=>{
	item.addEventListener('click',function(e){
    console.log(this,1);
      e = e || window.event;
      e.preventDefault();
      let id = this.getAttribute('data-var_id');
      let formData = {
        'items': [
          {
            'id': id,
            'quantity': 1
          }
        ]
      };

      fetch('/cart/add.js', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify(formData)
      })
      .then((resp) => { 
        return resp.json();
      })
      .then((data) => {
        document.documentElement.dispatchEvent(new CustomEvent('cart:refresh', {
            bubbles: true
          }));
        document.querySelector("a#panier_icon_ajax").dispatchEvent(new Event('click', { 'bubbles': false }));
        
      })
      .catch((err) => {
        console.error('Error: ' + err);
      })
  });

});

It comes from this line

document.querySelector("a#panier_icon_ajax").dispatchEvent(new Event('click', { 'bubbles': false }));

What can I use to make the side cart also show on Ios(iphone) without the redirect?

Merci
