Help adding Intercom Fin to our Zendesk Help Center (Guide)

I’m trying to add Intercom Fin to our Zendesk Help Center and need some help with the JavaScript code they provide. Specifically, I’m not sure what I need to do to edit the snippet provided and replace the example variables (highlighted in red) in the window.intercomSettings object with our own variables for user data. Our Zendesk Help Center does not require users to sign in, so I’m not sure what to replace the variables with.

Any help would be much appreciated!
