This is not a fault in gmailjs and the example repo. These repos are not “learn JavaScript” support forums.

Knowledge about JavaScript is a prerequisite to use this library.

You need to completely disregard gmailjs, take a break, read up on how modern day JS development with script-bundling (browserify, webpack, etc) works.

When you understand that, using gmailjs will be easy.

we decided to use some other API due to no support of new GMAIL UI

This is an on-going effort. And gmailjs is a open-source project. Nothing gets added, unless an active contributor decides to add it.

I did more testing with NEW, most of events not working

This is a known issue. It’s being worked upon. By active contributors who needs those events working. They’re submitting patches, and so can you.

That’s entirely your call. No hard feelings.
