Export zeplin SVG assets. Open the styleguide site on the zeplin website, run the script in your console, and then make sure to click each asset every second.

zeplin-export.js

function refreshData()
{
  let index = 1 // On AND, the SVG download button is the second, so we need [1]. On iOS, the PDFs are also at [1]. See https://i.imgur.com/hoWIniV.png.
  document.getElementsByClassName("downloadButton")[index].click() 
  setTimeout(refreshData, 1000);
}


refreshData(); // execute function

best script ever!
