It looks like you added it to the description. But you also added there "it is not for AI or NFT"... CC0 means public domain that allows everything. So it is good for AI or CC0 is not for this situation.
NFT is a bit more gray zone for it because you try to make work public domain when it is under CC0 that allows everything. But at the same time NFT is about selling something unique...
