Prisma

shouldn't this `Create` permission only allow you to create a `Customer` if your authenticated `User.id` matches the `Customer.createdBy.id`?
```
query ($user_id: ID!) {
  SomeCustomerExists(filter: {
    createdBy: {
      id: $user_id 
    }
  })
}
```

what's strange is, the mutation to create a customer uses `createdById`, I would have thought the permission would have allowed you to do:

```
query ($user_id: ID!) {
  SomeCustomerExists(filter: {
    createdById: $user_id 
  })
}
```

maybe that's why the permission isn't working?

ok, got it working, I needed to do a relation permission:

```
query ($user_id: ID!, $createdByUser_id: ID!) {
  SomeUserExists(filter: {
    AND: [
      { id: $user_id },
      { id: $createdByUser_id }
    ]
  })
  SomeCustomerExists(filter: {

  })
}
```

looks like this works for a create permission

```
query ($user_id: ID!, $input_createdById: ID!) {
  SomeUserExists(filter: {
      AND: [
        { id: $user_id },
        { id: $input_createdById }
      ]
   })
}
```
