HttpResponseRedirect in Django. I can't configure redirect to the desired page

After filling out the form, a page should appear where it says that the form has been submitted successfully. But in my code it gives an error:

Page not found (404)
Request Method: GET
Request URL:    http://127.0.0.1:8000/candidate/done.html
Using the URLconf defined in ntkproject.urls, Django tried these URL patterns, in this order:

1. done
2. 
3. grappelli/
4. admin/
The current path, candidate/done.html, didn't match any of these.

I can't set up a redirect to the page done.html

Here views.py:

from django.http import Http404, HttpResponseRedirect
from django.shortcuts import render, redirect

from .forms import AnketaForm
from .models import Anketa

def anketa_create_view(request):
    if request.method == 'POST':
        form = AnketaForm(request.POST)
        if form.is_valid():
            form.save()
        return HttpResponseRedirect('candidate/done.html')
    else:
        form = AnketaForm()
    return render(request, 'candidate/anketa_create.html', {'form': form})

Urls.py (apps/candidate)

from django.urls import path

from . import views

urlpatterns = [
    path('', views.anketa_create_view, name = 'anketa_create_view'),
    ]

Urls.py

from django.contrib import admin
from django.urls import path, include

from candidate.views import anketa_create_view

urlpatterns = [
    path('done/', anketa_create_view),
    path('', anketa_create_view),
    path('grappelli/', include('grappelli.urls')),
    path('admin/', admin.site.urls),
]

Done.html

{% extends 'base.html' %}
