How can I save user name when Apple sign in?

[playma]

I use Facebook Login, Google Login, they can save user name and avatar automatically. But I use Apple login, get nothing...

Can someone else help me? Thanks

This is my setting.

class AppleLogin(SocialLoginView):
    authentication_classes = (JWTAuthentication,)
    adapter_class = AppleOAuth2Adapter
    callback_url = '/api/rest-auth/apple/callback/'
    client_class = AppleOAuth2Client
