Query regarding creating abandoned checkout using cart API

I am developing an app where I will be creating and updating carts using the Storefront API. Now, to push a cart into the “Abandoned Checkouts” section on Shopify, I currently use the checkoutCreate mutation. Checkouts created through this method appear immediately in the “Abandoned Checkouts” section on the Shopify dashboard.

Shopify is now deprecating the Checkout API and the migration guidance suggests using cartCreate instead of checkoutCreate. However, when I create a cart using cartCreate with the essential fields (lines, buyerIdentity, and deliveryAddress), it doesn’t consistently appear in the “Abandoned Checkouts” section.

It seems that while a cart created with these fields is considered a checkout (as I can generate a checkout URL), it isn’t automatically recognized as an abandoned checkout. I couldn’t find any documentation about marking a cart as an abandoned checkout via the Cart API. Could someone please help me with this?
