Maatwebsite excel set watermark in laravel

I am using laravel 9 and using Maatwebsite. I want to make watermark in excel. Here I did

class myExport implements FromView, WithEvents ,WithDrawings
{

  public function view(): View
   {
     return view('report');
   }

   public function drawings()
    {
    $drawing = new Drawing();
    $drawing->setName('Background Text');
    $drawing->setDescription('This text ');
    $drawing->setPath(public_path('assets/img/draft.png'));
    $drawing->setCoordinates('A1'); 

    return [$drawing];
}

But this image not appears in background. Also it will be ok if I set any text

Thanks in advance.............
