After finding a product in the V5 product catalog, how do I add it to the cart?

1. Find the target product in the product catalog list (you can see the SKU, product name, price, inventory, and other information). 2. Click the shopping cart icon (🛒) on the far right of that row, and the product will be added to your cart. 3. Click the "Shopping Cart" icon in the top-right corner to view all products in your cart and proceed with the subsequent purchase process.
