Hi, i was checking out your example and it seems really interesting. I noticed that you store the users and access tokens in a shared database and all other models are separated. It would be better if the users also exist in the specific tenant databases. Right now, the users from the different tenants are mixed. I tried separating them but ran into issues when the access token is validated. Also why have a User and a Person model when the Person model can inherit from the User object?
