password_reset_confirm and password_reset_complete in Django

Question

I have used Django's built-in password reset functionality. everything is working fine but when I open the password reset link from Gmail browser redirects me to Django's built-in "password_reset_confime " template instead of my custom template I don't know where I have done mistake in rendering custom template please help me to do that its really appreciated

usrl.py Code

app_name="accounts"
urlpatterns=[
path('password_reset/',auth_views.PasswordResetView.as_view( template_name='password_reset.html', success_url=reverse_lazy('accounts:password_reset_done')),name='password_reset'),
path('password_reset_done/', auth_views.PasswordResetDoneView.as_view(template_name='password_reset_done.html'), name='password_reset_done'),
path('password_reset_confirm/<uidb64>/<token>/',auth_views.PasswordResetConfirmView.as_view(template_name='password_reset_confirm.html',success_url=reverse_lazy('accounts:password_reset_complete')),name='password_reset_confirm.html'),
path('password_reset_complete/', auth_views.PasswordResetCompleteView.as_view(template_name='password_reset_complete.html'), name='password_reset_complete'),
]

And I also want to implement a feature while entering an email id into the input field, I want to check if the user's entered email exists or not, if do not exist I want to show an error message "this email id is not existed"

please help me to implement this feature and provide a solution for rendering my custom password_reset_confirm.html and password_reset_complete.html pages
