Describe the Bug

As i am trying to get the directus_refresh_token via a jwt (for localhost development or mobile app) it is not possible for me to obtain it.

See:
directus/v8-archive#1981
since i think that if the normal login can this, the sso auth will also allow this:
https://docs.directus.io/reference/api/system/authentication/#login

1. Call SSO Provider using https://mydomain.com/projectname/auth/sso/google?mode=jwt&redirect_url=https://myvueappdomain.com/callback

Now Step 2 is not working.
2. Getting https://myvueappdomain.com/callback?request_token=xxxxxxx. I got that token

To Reproduce

oAuth login but with jwt or json mode instead of cookies.

I think in /src/controllers/auth.ts at line 332 it could either be implemented or is missing ?
