Gumroad bulk download

gumroad_bulk_download

// Run this in the content download page and it will trigger download for everything


var sleep = (milliseconds) => {
  return new Promise(resolve => setTimeout(resolve, milliseconds))
}

var waitTime = 1500; //ms

var x = $( "button:contains('Download')" );

for(var i = 0; i < x.length ; i++)
  {
    (function(idx) {
      // Wait needed because browser blocks network calls if you make too many too fast
      sleep(i * waitTime).then(() => {
    		x[idx].click();
			});
   	})(i)
  }

Can anyone please help me to download from the beginning and how to code it please.. that'd be great help thankyou
