Cant get spore CD key on steam 2021

So I have bought spore and i cant login to my spore account, so I went to find out why and came to the conclusion I needed my CD key to link it to origin but i cant find the cd key in steam for some reason and I have searched where it is and just cant find the spore cd key on steam (I don't know if the cd key is gone after 2020 or something) if the cd key is gone then how am i meant to log in?
