Finding Event Properties Visibility in Updated Lexicon UI

Hi all - I'm trying to set some event properties to visible (which have been hidden by default). I'm seeing the message below. I think there was a Data Audit button in the Lexicon where we would specify events & properties previously, but I can't see that now (since the UI was changed). Does anyone know where I can find that function now? Or if that's been removed, how to set new properties to visible?
