Can you add a discount code field in the cart without using a custom app?

[cadavid]

I want to add a field where the discount coupon can be added from the cart and apply such discount to the items before checkout. I've been doing research on cart discounts  and have seen documentation where it talks about at https://shopify.dev/themes/pricing-payments/discounts

But when I want to use those variables, they don't apply to discount coupons. only for automatic discounts. The only thing I've found are apps like Dcode that do this. I have seen responses in other threads about this, but not an official response on whether the only way to access and apply discounts within the cart is through apps. Is it possible to do this without the need for a custom App?

Hi, Welcome to Shopify Community. 

Definitely, this is possible with an app or with a custom solution too. There are multiple other apps that offer the same functionality - Discount on cart  pro edition and Dcart 
You can try them. Also, a custom solution can be implemented for this.
