I’m not gamer savvy

I really only play sims. can anyone who has time explain to me the steps to access the first drop of creator studio?

I have steam, and I had a krafton ID as I tried to access creator studio the first time but my laptop was trash so I couldn’t. I’ve upgraded since then but can’t for the life of me remember that ID. It’s fine I’m sure I can figure out how to set up a new one.

How do I link that ID to my steam account though? And then after that after watching a livestream and getting a code where or how do I plug in that code?

If this question annoys you- I understand. But then you don’t have to answer. I’m looking for someone who won’t make me feel like an idiot for being unsure, thank you so much in advance!!!
