Attaching PDF S3 bucket URL with meteor mail

How to attach the PDF file URL with email in the mail? I’ve one pdf which is stored in the s3 bucket. The URL of that pdf file i.e https://s3-us-west-1.amazonaws.com/bucket-name/demo.pdf.

I know how to send the mail in a meteor. I know the one approach of sending pdf attachment would read file from the URL and send the read data with email as following -

Email.send({
   from: `abc@gmail.com`,
   to: 'cde@gmail.com',
   subject: 'mySubject',
   text: 'sssswwwwws',
   attachments: [{'filename': 'stackoverflow23.pdf', 'content': data, 'contentType': 'application/pdf'}] 
});

Here the data refer to fs.readFile(url) response.

But can we send the file URL directly with email? So we don’t need the above implementation (read file).
