Question about Shopify and checkout

Hi,
I found a product I want to dropship. This is a personal jewellery that the customer can choose to write their nametag in.
When ordering from aliexpress it is a step "Review and confirm your order" where the customer are supposed to write down their name in the comment so the company gets the info for the order.

The problem with the checkout in my shopify store is that there is no option for comments. So the customers cant leave any info.
Is it somehow possible to fix this problem?

Edit the code or hire someone to do it for you if you can't + not good idea to share your niche
