Kieran, thank you for following this tutorial and for joining our Auth0 Community. We’ll get in touch with the author to take a look at these outstanding questions I apologize for the delays to address that concern.
One question, please: what version of Electron are you using? We are currently having issues with Electron 7+ and the guidance that we have provided is not working. We are in the process of updating it. You may see more details on this in my reply to Siva above
