Hi. thanks for this article and the interesting samples to deploy some product on Google Cloud.
I was just a few disappointed at the beginning of the article when you recommend to use a service account key file (a bad practice!!) especially is you grant a huge amount of permissions to your service account (editor role)!!
And a final remark about a .exe file: all your readers don't use Windows OS. Think about linux, macos and ChromeOS users ;)
