GraphQL + React Real-estate Booking API

Please, create an application that works with GraphQL.

We have 3 mongoose schemas that reflect entities of our application:
User, Relestate and Bookings

User can be owner of many real-estates.
Also, user can book real estates. Booking entity stores information about this.

Application should handle the queries for receiving

• all users ()

Take the namings from provided examples.
Also, note that drilling through related properties should be possible at any depth.
