React-Admin Convert generateData from 'data-generator-retail' in aws amplify schema.graphql

I'm working on a project where I'm trying to reproduce the react-admin demo https://github.com/marmelab/react-admin/tree/master/examples/demo in a project based on aws amplify.

I am using this library https://github.com/MrHertal/react-admin-amplify to properly establish the connection.

The react-admin demo uses data-generator-retail (https://github.com/marmelab/react-admin/tree/master/examples/data-generator) in conjunction with "fakerest", "ra-data -fakerest "and" fetch-mock "to set the demo data sourc, and show this data structure:

**customers**
id: integer
first_name: string
last_name: string
email: string
address: string
zipcode: string
city: string
avatar: string
birthday: date
first_seen: date
last_seen: date
has_ordered: boolean
latest_purchase
has_newsletter: boolean
groups: array
nb_commands: integer
total_spent: integer

**categories**
id: number
name: string

**products**
id: integer
category_id: integer
reference: string
width: float
height: float
price: float
thumbnail: string
image: string
description: string
stock: integer

**commands**

customer_id: integer
basket: [{ product_id: integer, quantity: integer }]
total_ex_taxes: float
delivery_fees: float
tax_rate: float
taxes: float
total: float
status: 'ordered' | 'delivered' | 'canceled'
returned: boolean

**invoices**

**reviews**
id: integer
date: date
status: 'pending' | 'accepted' | 'rejected'
command_id: integer
product_id: integer
customer_id: integer

comment: string

Does anyone know the best way to represent said schema in aws amplify's "schema.graphql" file to reproduce exactly the same result?

My apprenticeship attempts led me to this:

type customers
@model
@auth(rules: [
    { allow: groups, groups: ["admin"] }
  ])
  {
id: ID!
first_name: String
last_name: String

address: String
zipcode: String
city: String
avatar: String
birthday: AWSDateTime
first_seen: AWSDateTime
last_seen: AWSDateTime
has_ordered: Boolean
latest_purchase : AWSDateTime
has_newsletter: Boolean
#groups: array #Doubt about which type of data is equivalent
