How to use two different model for Session authentication

First of all, thanks Adonis for this cool framework. I’m just loving it and start developing. I have a problem, that how to use three different model for the Session authenticator. But I don’t know how to toggle it. Here is the Session block in auth.js file

session: {
serializer: ‘lucid’,
model: ‘App/Models/User’,
scheme: ‘session’,
uid: ‘email’,
password: ‘password’
},

After goggling get the url https://github.com/adonisjs/adonis-auth/issues/121

Tired there approach, but no luck. Please guide me how can I achieve it and share the auth.js file. Again, thanks for the Adonis.
