How do you make clien_secret not hashed to make drf_social_oauth2 /auth/convert-token work?

[slavkojovanovic]

In created a new application but I don't see the check box option for not hashing the client_secret.
This can be seen in the screen shot on this page: https://drf-social-oauth2.readthedocs.io/en/latest/application.html.
According your instructions hashed client_secret does not work with convert-token. I get the error stating this.

I do not have this option in my admin console.

How do I surface it and/or is there any workarounds.
Thank-you
