Keycloak Dynamic Update Profile Form question for 15.0.1

I’m using Keycloak 15.0.1, when have user profile feature enabled on realm, from user account page, my custom profile attribute is not dynamic showing on account tab, that page only shows username/email/first name/last name.

According to the offical wiki the Dynamic Update Profile Form should looks like this
user profile update profile

Does any one knows how to access the Dynamic Update Profile Form which dynamicly shows my custom attributes as well?
