drf social-oauth2 access_denied ,Your credentials aren't allowed

Question

I'm trying to use this package https://github.com/RealmTeam/django-rest-framework-social-oauth2

In Google Example

When I try to request an access_token by

curl -X POST -d "grant_type=convert_token&client_id=<django-oauth-generated-client_id>&client_secret=<django-oauth-generated-client_secret>&backend=google-oauth2&token=<google_token>" http://localhost:8000/auth/convert-token

it's saying

{"error":"access_denied","error_description":"Your credentials aren't allowed"}

What should I put in

django-oauth-generated-client_id and django-oauth-generated-client_secret

is that the thing where you create new application or should I put the google's client and secret ids

I try both but still not working.

Also in

token=<google_token>

I try to put the Authorization code or the access_token in this image but still not working

enter image description here

Can someone help thank you
