How to reset Webflow Cart quantity also reset the cart product after redirect to contact page

I am using Webflow e-commerce I have set all of the things. But I don’t need to do transactions so when I add products to the cart then in the cart panel from the right sidebar at the bottom I have created one of my own custom checkout buttons which redirects to the contact page. Now I want when it redirects to the contact page in the meantime I want the cart should be empty and also the cart panel where my product is shown this will be also clear with no products. How can I do that? Please help me, or anyone, to write the custom code.
