OAuth2

I'm trying to associate user with multiple social accounts in Django Rest Framework.
After user login, user can associate with social accounts (it doesn't matter same email or different email).
Now I am using the library [drf-social-oauth2]
I have done signIn/singUp part. According to [Social_Auth_Pipeline], I added this code to associate user

SOCIAL_AUTH_PIPELINE = (
  'social_core.pipeline.social_auth.social_details',
  'social_core.pipeline.social_auth.social_uid',
  'social_core.pipeline.social_auth.auth_allowed',
  'social_core.pipeline.social_auth.social_user',
  'social_core.pipeline.user.get_username',
  'social_core.pipeline.social_auth.associate_by_email',
  'social_core.pipeline.user.create_user',
  'social_core.pipeline.social_auth.associate_user',
  'social_core.pipeline.social_auth.load_extra_data',
  'social_core.pipeline.user.user_details',
)

The endpoint "http://localhost:8000/auth/convert-token" can handle the singin/singup using social auth.(eg. Facebook, Google)

social_core.pipeline.social_auth.associate_by_email managed to associate the user if same email.

What I have tried:

My Question is
How can I connect/associate Social Accounts (* different email/same email) with current login user using drf_social_oauth2?

Do I need to add field in user table to associate? OR Do I need to add something to setting.py?...
Please advise me.
Thank you.
