Okay, I ended up just getting the actual URLs by doing this in the Chrome Dev tools

const tds = document.querySelectorAll('table tbody tr td span.DPvwYc.QiuYjb.ERSyJd');
const urls = Array.from(tds, td => td.getAttribute('data-value'));
copy(urls.join('\n'));

but yeah, seems a bit weird to have an export option that doesn't really give you what you need, and you have to create your own way of making an export 🤷‍♂️
