Auth0 Implementation With Existing Laravel Auth Structure

I am facing an issue with the existing Laravel Auth structure while trying to implement Auth0 as well. We are using the auth user object and auth id in our business logic at multiple places in the application already. We are using Auth::id() and Auth::user() information that are related to our user model. However, by implementing the Auth0 authentication now we are unable to use Auth::id() and other Auth user information because now the user is authenticated from the Auth 0.
So is there any way by using which we can overwrite or add some custom attributes in the Auth0 user object, that may be available all the time during the user Auth Session?
