Registration & /authorize endpoint

Hi,

I’ve been using the /authorize endpoint

https://${myOktaDomain}/oauth2/default/v1/authorize

to allow the users to login through the browser. Now I want them to register via the form that is also available when clicking on the “Sing Up” text at the bottom, but I would like to access directly to the registration form when calling the endpoint from my app instead of showing the initial login form. I’ve been looking for documentation about this, but I wasn’t lucky.

Basically I’m looking for this to be the first screen when I make the previous API call:

Thanks,
Aleix
