On start the "Sign up" should displayed with universal lock

I migrating to the new universal lock. In my old options I had the parameter initialScreen where I can choose between the login and signUp screen.
What is the parameter for changing to the “sign up” screen in the universal lock on start?

Hey there!

Unfortunately in the new version of the UL there is no option to set the default tab as of now. You can place that as product feedback here:
