KFC Duoble Stacker BETA CODE

Hello,

I purchased this amazing stacker it was very delicious and one the best experience of my food life. I wanted to enjoy the Diablo 4 as much as I enjoyed the stacker, but that was not the case. I ended up with more than I can chew. I inserted the code in my account to unlock the beta but I can seem to find the game. It shows up in my library as DIABLO 4 Beta but cant seem to do anything else other than just look at it. NO "install now’’ or "play now’ button.

PLEASE HELP
