Changing "Wording" of the checkout page

Hello! I am looking to modify the wording of "Discount" below under checkout:

Can anyone help me finding this code?

You can try these:

Using javascript:

<script>

el = document.querySelector("[class^='CheckoutTotal-label-']")
el.innherHTML = "Your word"

</script>

or Using css :

[class^='CheckoutTotal-label-'] {
  visibility: hidden
}

[class^='CheckoutTotal-label-']::before {
  content:'Your text'; 
  visibility: visible;
}

This selector [class^='CheckoutTotal-label'] is trying to find element who has attribute class and the value of attribute starts with CheckoutTotal-label-

🙂 ignore my post @tuanphan is right, I totally missed that its checkout page 

That’s very sad. Thank you both for your input!
