Integration of signup card into a webapplication screen

Hi there

We are using Auth0 for authentication in our web application. Now we are looking for a way to integrate the signup card into an existing screen in our onboarding, is this possible? I have only found ways to customize the login/signup card, but we would also like to have other UI elements (e.g. an progress indicator for onboarding) on the screen that cannot be generated in the customization feature of auth0.

Thank you for your help.
