Why is my Blackboard missing a new key button?

I just created a blackboard and its missing the new key button. I’ve tried creating new ones and restarting my editor but I still don’t see it. What can I do? I’m running 5.4.4

You should open up the blackboard window. Go to the “Window” menu on the top left of your screen and click on “Blackboard”

I found it thank you!
