Identify backend users

[leoschml]

Hi there,
I have successfully integrated the messenger via JavaScript to show up only on the backend of my WordPress website.
However, I want to make use of the user identification, but I am unfortunately a noob when it comes to coding. Can someone help me how to pass the variables (user-id, e-mail, signup date) to Intercom via JavaScript? So no custom metas, just the standard WordPress user information.

I would really appreciate any help. Thank you very much! 🙏
