React Instant Search Insights and userToken question

Hey I was just looking at

In there the code for the userToken reads

let userToken = '';
window.aa('getUserToken', null, (err, algoliaUserToken) => {
  if (err) {

  userToken = algoliaUserToken;

For the rest of the page it doesn’t look like userToken is used anywhere else? Is this enough to set the userToken?

Hi, you can send the usertoken using code like this example.
