User Attributes in Oauth

Hello,

Is there a specific scope to get the custom user attributes from oauth? This is what oauth is returning from the userinfo endpoint-- I need to be able to get access to custom attributes set from the register flow.

```
{
sub: '362452e8c707471dd6fe96120c37b70972e4f6f0e996b6eeef5f1df20168ad2a',
email: 'test@test.com',
email_verified: true,
name: 'Test Account',
given_name: 'Test Account',
preferred_username: 'test',
nickname: 'test',
groups: [ 'Customer Authentication' ]
}
```

Attributes set are showing correctly within Authentik, I'm just not sure how to pass them to oauth.
