I'm using the Avenue theme and I'm looking for help to add a link to the 'out of stock' button on my product pages as well on my collection pages. I know how to change the text from "Out of stock" to e.g. 'Contact us for a quote'. But I need help to make this button clickable, adding code to it that opens our contact form (https://trenzyme.shop/pages/bulk-or-individual-order-trenzyme). So if "track quantity" is enabled and available quantity = 0 for a product, the buttons "Add to Cart" and "Buy it now" shouldn't be displayed, but the descriped clickable button "Contact us for a quote" linking to the contact form should be displayed. And the information below the buttons "Need a quote for an individual request or for a bulk order? Please contact us" should be displayed in the out-of-stock-case.
