Django OAuth Toolkit - Register a User

Question

I looked at the Django OAuth Toolkit provider and resource documents, but all I can find is how to 'authenticate' a user, not as a registeruser.

I can configure everything on my machine, but I don’t know how to register a user using a username and password. I know that I am missing something very subtle. How do I accurately register a user and get an access token in exchange for my resource servers.

OR

Is it that I have to first register the user using the regular Django mechanism, and then get the token of the same?

django-allauth , . Amazon, Google Slack. , . Alexa "linking".

To integrate with the toy slice, I wrote, I added special code to create new django users based on their unique Slack user ID, completely skipping the OAuth workflow using Slack. Only after django users can exist can django-oauth-toolkit tokens be introduced for them.
