How to send imagefile from Airtable to WhatsApp using Airtable API

Hi, I’m writing a program that sends Airtable content to WhatsApp in Node.js. I’m facing a problem while sending the image file, I can only find a way that sends the image URL and not the image itself. How can I convert the URL to the image file?

Code for sending the image URL.

const img = record.get('Image');
imgurl = img[0].url
console.log(imgurl)

Help is appreciated, Thank you!
