Splendor premium access

[Gokihar]

Hey,
i bought Splendor game and within it I found code that says : Use this cade to unblock (...) INCLUDING premium to Splendor on BGA.
Its not to unblock premium access to BDA but looks like :
(3 letters)-(3 letters)-(number)-(4mixed numbers/letters)-(4mixed numbers/letters)-(4mixed numbers/letters)

I did not see any place to enter it ....

It seems to be an "Unbox now" code, this should help:

Those are Unbox now codes, that you can redeem at: https://gift.unboxnow.com/en/.

You'll then get a code that you will be able to use on BGA, at this address: https://boardgamearena.com/giftcodes
