Laravel syntax question with child relations for includes etc.

I'm trying to include the address in the company

It's fine on the singular model.

`/api/v1/companies/22?includes%5B%5D=address`

```php
$resourceOptions = $this->parseResourceOptions();
$query = $this->project::query();
$this->applyResourceOptions($query, $resourceOptions);
$result = $query->find($id);
```

But I cant figure out how to change the syntax when calling a child.

`/api/v1/projects/578/company?includes%5B%5D=address`

```php
$result = $this->project::find($id)->company;
```

Start by comparing the working `/api/v1/companies/22?includes[]=address` request with `/api/v1/projects/578/company?includes[]=address` and the two query snippets in the issue. No source file or test is named; done should be a documented or tested way for the child-company response to include its address.
