API Resource - with() being omitted from collection

Hello, I have an API Resource Contact.php which uses the with() method to append extra data to the response:

public function toArray($request)
    {
        return [
            'id' => $this->resource->id,
            'firstName' => $this->resource->firstName,
            'lastName' => $this->resource->lastName,
            'mobile' => $this->resource->mobile
        ];
    }

    public function with($request)
    {
        return [
            'status' => 'active'
        ];
    }

when I call the resource class new Contact($contact), the with() data is returned i.e. status:active:

{
    "contact": {
        "id": "1",
        "firstName": "John",
        "lastName": "Doe"
    },
    "status": "active"
}

However, when I turn this into a resource collection new ContactCollection($contacts) or Contact::collection($contacts), the with() data is not returned:

"contacts": [
        {
            "id": "2",
            "firstName": "Jane",
            "lastName": "Doe"
        },
        {
            "id": "3",
            "firstName": "Jim",
            "lastName": "Smith"
        }
]

Does anyone know how I can get the with() data returned in a resource collection?
