CartDiscountValue of type giftLineItem is supported ?

Hi, Can you please confirm if Syncing cart discounts with a CartDiscountValue of type giftLineItem is supported ?

i see there is mention about this in main readme, wanted to check if this issue is fixed or still underdevelopment with any timeline for release?

https://github.com/commercetools/commercetools-sync-java/blob/master/docs/usage/CART_DISCOUNT_SYNC.md

https://github.com/commercetools/commercetools-sync-java/issues/411

(we have discount values that are using product reference, channel references and we observe those are not getting synched).

Thanks

Start with docs/usage/CART_DISCOUNT_SYNC.md and the linked issue #411 to determine the current support status for giftLineItem values and product or channel references. Review the relevant cart discount sync entry points and tests, if identified there; done should mean the supported behavior or implementation scope is clearly established and documented.
