How to create a simple confirmation view on Django Admin like the default delete view works

admin.py

from django import forms
from django.contrib import admin
from django.template.response import TemplateResponse


class RegularCreationAdminForm(forms.ModelForm):

    class Meta:
        model = ReactivationCoupon
        fields = [
            'field1', 'field2', 'field3', 'field4',
            'field5', 'field6',
        ]
 

class RegularCreateViewAdmin(admin.ModelAdmin):
    list_display = ('field1', 'field2', 'field3', 'field4', 'field5', 'field6')
    search_fields = ('field1',)
    ordering = ('field1', 'field2',)

    form = RegularCreationAdminForm

    def _changeform_view(self, request, object_id, form_url, extra_context):
        if request.method == 'POST' and "_confirmation" in request.POST and not object_id:
            ModelForm = self.get_form(request)
            form = ModelForm(request.POST, request.FILES)
            form_validated = form.is_valid()
            if form_validated:
                new_object = form.save(commit=False)
                context = {
                    **self.admin_site.each_context(request),
                    'obj': new_object,
                    'opts': self.model._meta,
                    'form': form,
                }
                return TemplateResponse(
                    request, 'admin/app_name/model_name/form_confirmation.html', context)

        return super()._changeform_view(request, object_id, form_url, extra_context)

change_form.html

{% extends "admin/change_form.html" %}

{% block submit_buttons_bottom %}
  <input type="submit" value="Confirm" name="_confirmation">
{% endblock %}

form_confirmation.html

{% extends "admin/base_site.html" %}
{% load i18n l10n admin_urls %}

{% block bodyclass %}{{ block.super }} app-{{ opts.app_label }} model-{{ opts.model_name }} delete-confirmation
  delete-selected-confirmation{% endblock %}

{% block breadcrumbs %}
  <div class="breadcrumbs">
    <a href="{% url 'admin:index' %}">{% trans 'Home' %}</a>
    &rsaquo; <a href="{% url 'admin:app_list' app_label=opts.app_label %}">{{ opts.app_config.verbose_name }}</a>
    &rsaquo; <a href="{% url opts|admin_urlname:'changelist' %}">{{ opts.verbose_name_plural|capfirst }}</a>
    &rsaquo; {{ title }}
  </div>
{% endblock %}

{% block content %}
  <ul style="padding: 0">
    This is a confirmation view!
  </ul>
  <hr>
  <br>
  <form action="" method="post">{% csrf_token %}
    <div class="submit-row">
      <input type="submit" name="_save" value="{% trans "Yes, do it!" %}"/>
      <a href="#" onclick="window.history.back(); return false;"
         class="button cancel-link">{% trans "No, take me back" %}</a>
    </div>
    <fieldset class="module aligned" style="visibility: hidden;">
      <div class="form-row hidden">
        {{ form }}
      </div>
    </fieldset>
  </form>
{% endblock %}

If we want confirmation for a single admin model..is there a way to make it work?
