问题
I'm using firebase's pre-build auth UI and which seems very helpful to me reducing a lot of boilerplate code. But I'm facing some limitations. For email registration using prebuild auth UI, there are only the three fields I'm getting (Email, First and last name, password) showing the attached image below.
But I need to add some extra fields (Address, Postal code, etc) and apply some business logic like confirm password, password strength check, etc.
I got a solution from another question but it is not applicable for pre-build auth UI.
