How do I customize django-two-factor-auth for existing REST API for login

[Pal-Sandeep]

I am currently using REST API for user login. Now want to add two factor authentication to my existing Login api.
In django-two-factor-auth there are views provided by default, and I want to customize them according to my API response.

I was able to integrate with DRF, using token authentication.
There are several caveats, but it is possible.
I needed to create a custom auth class, create a custom permission class, change the login view and create the setup and 2FA verification, refresh and backup tokens listing views.
