How to add a “buy now” button to sales page?

This is for Woocommerce on WordPress but I’m open to other suggestions outside of Woocommerce to fix this.

I have a sales page (built with Kadence blocks, separate from the product page) where I’d like to add a button that takes the user to the checkout page.

I’ve tried to add a single product black or featured product black but the “buy now” button leads to the product page whereas I’d like it to directly to the cart.

Any idea of how to fix this? Also willing to pay for alternative solutions if the price is right.

Appreciate y’all helping a beginner out!
