Maatwebsite Excel - 在地图中导出图像

this is my scenario:

Laravel v5.5.44
maatwebsite/excel 3.1.3

I'm exporting a list of object using Maatwebsite Export classes. In my map() method all is working fine, but now I need to export images linked to my items. I've tried this way:

public function map($item):array
{
    //....
    $this->path = Storage::disk("artworks_images")->path($item->$key);
    $this->drawings();
    //...
}

Where my drawings method is:

public function drawings()
    {
        $drawing = new \PhpOffice\PhpSpreadsheet\Worksheet\Drawing();
        $drawing->setName('Cover');
        $drawing->setDescription('Cover');
        $drawing->setPath($this->path);
        $drawing->setHeight(36);
        $drawing->setCoordinates("A2");
        return $drawing;
    }

I've added the WithDrawings concern to the class.

It doesn't throw exceptions, but no images are shown.

Is there a correct way to use the drawings method in map()? (And, if it is possible, to auto-set the current coordinates like columns with primitives data?)
