WPS Office add-in development

I am trying to build a couple of WPS Office add-ins and have started looking into what's available for developers. I found some npm dependencies that look relevant but the documentation is predominantly in Chinese which makes it hard to evaluate what I'm actually working with and follow the development guides properly.

I’m looking for practical English language resources that actually walk through the add-in development process rather than just high level API references. Things like setting up the development environment, understanding the add-in architecture, working with the available APIs, and getting something deployed and working end to end.

Is there an official English language developer documentation portal from WPS that covers WPS Office add-in development comprehensively? Are there any community maintained guides, GitHub repositories with example add-ins, or developer forums in English that are active enough to be useful?
