How to customize the registration form with External User Registration plugin? Fields missing after

[NicolasNguyen]

Hi everyone,
I want to customize the registration form in ServiceNow. I followed the official instructions and added the "External User Registration" plugin. However, when I try to add fields to the registration form, I can't see the fields I created for dragging and dropping.
Has anyone encountered this issue? How can I make my custom fields appear in the registration form?
Thank you!

Where did you add them? What isn't showing? We don't have access to your instance, so screenshots or more information on how/where you did what would be very helpful.
