How can I add an action to the Django User admin page?

I'm using Django 3.0. I want to add an action to the User ChangeList in the admin.

The documentation for admin actions indicates that to add an action to an admin page, I need to add either the method or a reference to it to the Model's admin.ModelAdmin subclass in admin.py:

# admin.py  from django.contrib import admin    def make_published(modeladmin, request, queryset):      queryset.update(status='p')  make_published.short_description = "Mark selected stories as published"    class ArticleAdmin(admin.ModelAdmin):      list_display = ['title', 'status']      ordering = ['title']      actions = [make_published]  

or

# admin.py  from django.contrib import admin    class ArticleAdmin(admin.ModelAdmin):      ...        actions = ['make_published']        def make_published(self, request, queryset):          queryset.update(status='p')      make_published.short_description = "Mark selected stories as published"  

Since the User Model's admin.ModelAdmin subclass is in the auth system and not in my admin.py, though, I don't know where to put the code for this case.

I tried following user Davor Lucic's answer to a much older but similar question

from django.contrib.auth.models import User    class UserAdmin(admin.ModelAdmin):      actions = ['activate_user','deactivate_user']        def activate_user(self, request, queryset):          queryset.update(status=True)        def deactivate_user(self, request, queryset):          queryset.update(status=False)        activate_user.short_description = "Activate user(s)"      deactivate_user.short_description = "Deactivate user(s)"    admin.site.unregister(User)  admin.site.register(User, UserAdmin)  

When I try this, the server halts with the error (full stack trace requested by responder):

I think the error might be with the register() and unregister() functions, but these have no documentation so I have no way of knowing.

Is there a simple, functioning way to add an admin action to the auth.models.User Model?
