How do I add a custom link, link for a collection button, to a contact page

so currently on my stores home page I have a collection list with 4 collections added to them. 3 of them are for products but I want the 4th button to be a link to my contact page. I can’t find a tutorial on doing anything like this anywhere I have no idea how to do it lol. Any help would really be appreciated.

The problem is, is that natively collection buttons are used to link to a list of products and there is no settings in shopify to change it to the page I want to. Perhaps I have to code something or there something I just don’t know about?

  1. In the left-hand sidebar, under the “Sections” folder, locate the file that corresponds to your homepage section. It might be named something like index.liquid or homepage.liquid.
  2. Open the file and look for the code that generates the collection list. It could be a loop that iterates over your collections.
{% if forloop.index == 4 %}
  Contact Us
{% else %}
  Shop Now
{% endif %}
​

Hello, I can’t see index.liquid or homepage.liquid I do have index.json though with this code…
