Trouble Finding New App Button in Dust App Creation Process

Hey ! I'm trying to build my first Dust App but can't see the "New App" button.

I have used the "Sign in with Github" button (usually I sign in with Google so I disconnected and reconnected with Github but I haven't seen anything different)
I have a valid OpenAI API Key in Developers > Providers section

I asked @help but s/he (?) didn't solve the problem. Any suggestion? Where should the button New App appear? Thanks!
