Template for PDF preview image

I followed Sonjas Cookbook to create PDF preview images. I want to add a template to the generated image. To apply the template I added the ‘template’ in the return value of the 'preview in the index.php: return new File([ 'filename' => $previewName, 'parent' => $this->parent(), 'template' => 'pdf-preview', ]); } How can I assign the template to the preview image?
