Account Linking Extension - Documentation Clarity

Attempting to use the Link Account Extension, and have a question about hiding Sign Up.

To prevent this, we send a query parameter to let the login page know that it should hide the Sign Up option. For this query parameter to take effect, however, you must customize the login page.

  1. Go to Auth0 Dashboard > Branding > Universal Login, and select the Login view.
  2. Enable the Customize Login Page switch to enable the custom editor below. In the editor, we’re going to add a new line to the Lock config.
  3. Toward the bottom of the object configuring the Lock widget, add the following line (after the closable setting): allowSignUp: !config.extraParams.prevent_sign_up,

There is no Lock config in the Universal Login HTML. How do I hide the sign up link when account linking is in play? Also, this same page mentions that,

But the tutorial is all about the setting this up for Universal Login. Can you provide guidance?

I hope this was helpful and if you have other questions please don’t hesitate to ask.

Thank you,
