Using screen hint but not landing on sign up page


I’m using the new universal login to link to my sign up page (with Java and Spring boot).

In my html template file, I link to the login using the following

a href="/oauth2/authorization/auth0?screen_hint=signup

but this takes me to the Login page not the Signup page. I tried to look up more from the documentation but based on it, I feel like that should work. Please let me know what I’m missing. Thank you!
