Add additional data to paginated resource laravel

This is the response of a GET request in an API with paginated data:

{
"current_page": 1,
"data": [
    {
        "id": 11,
        "user_id": 1,
        "text": "kek",
        "path": "public/gifs/mfNEs0XOK7X3ovIYdMwW67lemI4oRAos0ufxNeBm.gif",
        "created_at": "2020-09-18T01:32:47.000000Z",
        "updated_at": "2020-09-18T01:32:47.000000Z"
    },
    {
        "id": 12,
        "user_id": 1,
        "text": "kek",
        "path": "public/gifs/bFwa5My7NlkdtTFiqn6FXLzpcbaL9703phDEYQ5i.gif",
        "created_at": "2020-09-18T01:38:55.000000Z",
        "updated_at": "2020-09-18T01:38:55.000000Z"
    }
],
// ... rest of the pagination data
}

I need to insert a tags field in each of the models, which values comes from a Many To Many relationship.

Do I need to iterate the collection and insert each value manually or does laravel have a built in method for that?

Current function:

public function index()
{
    $expressions = $this->expression->paginate(20);
    
    return response()->json($expressions);
}

Load the relationship so it is part of the serialized output of the Model:

$expressions = $this->expression->with('tags')->paginate(20);

Assuming $this->expression is an instance of your Model.

"When an Eloquent model is converted to JSON, its loaded relationships will automatically be included as attributes on the JSON object."
