The codes posted on Kemono are still valid, one just has to find the correct set first (When you request your code from the game, it will tell you which post in patreon you should go to, you can use the number at the end to navigate the same post on kemono)Gotta wait for someone to share/leak it here then; or maybe someone shared it in the discord.
I don't remember how exactly I did it, but it took me less than 3 minutes to find the correct code.
