VerifyEmailView view doesn't work.

I have set up email verification as obligatory in the Allauth settings and as the documentation suggests created a new url with VerifyEmailView. However, I'm getting django.core.exceptions.ImproperlyConfigured: TemplateResponseMixin requires either a definition of 'template_name' or an implementation of 'get_template_names()' whenever I click the link that is sent to the mail.

Here is the email I got:

Hello from [example.com](http://example.com/)!

You're receiving this email because user test_username has given your email address to register an account on [example.com](http://example.com/).

To confirm this is correct, go to http://localhost:8000/api/auth/registration/account-confirm-email/MTI:1rDwxE:pQfOORIY0AOZN0AeweHmqOLDx2TmgVapR2V5y3Jruk4/
