Add Class in span attribute according to url

Question

I have a span attribute and need to insert a class to force the hide if it is within a URL, I want to do it fully in javascript.

Code I’m making

document.addEventListener('DOMContentLoaded', () => {
var classe = document.querySelector('span.price');
classe.forEach(function(classe){
  if(window.location.href == "https://www.myurl.com.br/product") {
classe.classList.add('force-hide');
  }});
});

.force-hide {
  display:none;
}

<div class="info-details"> 
<strong class="product name product-item-name"> 
<a class="product-item-link" href="https://www.myurl.com.br/product"> Product </a> 
</strong>
<div class="price-box price-final_price" data-role="priceBox" data-product-id="2293" data-price-box="product-id-2293">
<span class="price-container price-final_price tax weee"> 
<span id="product-price-2293" data-price-amount="13.9" data-price-type="finalPrice" class="price-wrapper ">
<span class="price">R$13,90</span>
</span> 
</span> 
</div></div>

I want to make sure that if it is in the given URL, it adds a force-Hide class in the span attribute.
