How do I redeem my NFT code?

Excuse me, I have a question about redeeming my NFT code. I recently received a notification stating that I had successfully purchased an NFT, but I'm a bit unsure of how to proceed from here. Could you please explain the steps I need to take to redeem my code and access my new digital asset? I've been following the cryptocurrency market for some time now, but this is my first time dealing with NFTs. Would you also be able to provide any additional information on how I can manage and protect my NFT once it's redeemed? I'd really appreciate your help in navigating this new territory. Thank you in advance for your assistance.
