Cocos-JS Native Build Instructions

Hi, I’m using Cocos2dx-JS v 3.17.1. I’ve built the game for web (Demo: https://playemojipop.com MUST BE PLAYED ON MOBILE MODE OR ON PHONE BROWSER). I want to compile the game for native devices but have been having difficulty (recent post).

I was wondering if anyone had up-to-date instructions for building the game on Android/iOS devices? Or any general advice or resources I should be looking at? Am a game designer by trade but having coding experience obviously. Thank you!!!
