Livebook.app Menu items missing

I’m sure this is a total noob question, but …

I have the Livebook app installed on my mac. I’ve updated to LiveBook 0.8.1. When I attempted to use the new Secrets management feature, the menu item is missing. I’m sure it has something to do with my install, but for the life of me, I can’t figure out what needs to be done.

Any suggestions?

Thanks,

Steve
