1. You cannot create objects in `init()` (line 465 to 469 extension.js): https://gjs.guide/extensions/review-guidelines/review-guidelines.html#only-use-init-for-initialization Move everything to enable and null them out in disable. 2. Also null out `_menu` in disable (extension.js). 3. You cannot create objects in global scope which the same as init (line 11 to 17 gIcons.js). Create a function there that can create and return them.
