Bonjour j ai une clé pour télécharger mais je ne vois pas ou l insérer pour télécharger

This page: https://x4fab.itch.io/ac-content-manager claimed this product came with a Steam key. Purchased, went to plug the key into Steam, and Steam says the key I was provided is invalid. Turns out that key isn't a Steam key, you plug it into Content manager itself (a download link is provided) to upgrade from the Free to the Paid version. Could be made more clear, please correct the line that says Steam key.

Hello, how much do you need to pay for the key to the "Content Manager" in rubles?! And do you accept payments via "Юmoney"?
