Hello, Siva. Welcome to our Auth0 Community 
Thank you for reading the blog post. As of now, this guidance only works with Electron 6. There were some changes made to Electron 7+ that prevent Auth0 from integrating correctly when following our current guidance. We are in the process of revising our guidance for Electron to support 7+ but also to be more resilient to change.
Please stay tuned. As soon as new guidance is up, I’ll be updating our different Electron-related channels with links to the new resources. I appreciate your time and understanding on this
