Documentation about aria selectors

[MathieuPuech]

Where can we find documentation about aria selectors?

I tried to reproduce the example of README.md and here is what I get (I removed the expect lines)

// npx @puppeteer/recorder https://www.google.com/?hl=en
const {open, click, type, submit, expect, scrollToBottom} = require('@puppeteer/
recorder');
open('https://www.google.com/?hl=en', {}, async (page) => {
  await click('aria/combobox[name="Search"]');
  await type('aria/combobox[name="Search"]', 'calculator');
  await click('aria/button[name="Google Search"]');
  await click('aria/button[name="1"]');
  await click('#rso > div.obcontainer.mod.NFQFxe > div > div.card-section.vk_c >
 div > div > div.SKWP2e > div > table.ElumCf > tbody > tr:nth-child(5) > td:nth-
child(4) > div > div');
  await click('aria/button[name="2"]');
  await click('#rso > div.obcontainer.mod.NFQFxe > div > div.card-section.vk_c >
 div > div > div.SKWP2e > div > table.ElumCf > tbody > tr:nth-child(5) > td:nth-
child(3) > div > div');
});

It does not seems to get the plus and equals
