Django Custom User Manager is not called when registering users on the admin panel

When a user is created on Django admin panel, objects = CustomUserManager() is not being executed. However, when I create a superuser from the CLI using python manage.py createsuperuser, objects = CustomUserManager() is executed.

Here is the model file

class CustomUser(AbstractUser):
    username = None
    email = models.EmailField(_('email address'), unique=True)
    name = models.CharField(verbose_name=_("first name"), max_length=50)
    stripe_customer_id = models.CharField(max_length=120)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['name']

    objects = CustomUserManager()

    def __str__(self):
        return self.name

Here is the customUserManager

class CustomUserManager(BaseUserManager):

    def create_user(self, email, password, name,**extra_fields):

        if not email:
            raise ValueError(_('The Email must be set'))
        email = self.normalize_email(email)
        customer = stripe.Customer.create(
            email=email,
            name=name,
        )     
        user = self.model(email=email,name=name, stripe_customer_id=customer.id ,**extra_fields)


        user.set_password(password)
        user.save()
        return user

def create_superuser(self, email, password,name,**extra_fields):
    """
    Create and save a SuperUser with the given email and password.
    """
    extra_fields.setdefault('is_staff', True)
    extra_fields.setdefault('is_superuser', True)
    extra_fields.setdefault('is_active', True)

    if extra_fields.get('is_staff') is not True:
        raise ValueError(_('Superuser must have is_staff=True.'))
    if extra_fields.get('is_superuser') is not True:
        raise ValueError(_('Superuser must have is_superuser=True.'))
    return self.create_user(email, password, name,**extra_fields)

Below is how I registered the admin panel.

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin

from .forms import CustomUserCreationForm, CustomUserChangeForm
from .models import CustomUser
from django.utils.translation import gettext_lazy as _


class CustomUserAdmin(UserAdmin):
    add_form = CustomUserCreationForm
    form = CustomUserChangeForm
    model = CustomUser
    ....

admin.site.register(CustomUser, CustomUserAdmin)

Below is the CustomUserCreationForm

class CustomUserCreationForm(UserCreationForm):

    class Meta:
        model = CustomUser
        fields = "__all__"
