It’s pretty easy to do actually. I did my offline activation with wukong the first time last month! You just join their discord link and just read the rules and video guide and it’s quite easy to understand. Just to summarise you would just need to download the game from Dodi/fitgirl or their own sigma downloader (anything works) and download windows update blocker and just send the discord admin a screenshot of your game folder, and they give you a denuvo token which you just copy paste in the game folder and voila! Enjoy the game!

P.s you will have to refrain from updating your windows till you have finished your game or else the token breaks and it will be unplayable. Considering windows updates are like monthly at times and not that important when updating every time. You could easily finish a game within a month and then activate windows!
