Description

The current icon for the app is not very well visible on dark mode.

There is a way to change the icon based on the theme of the browser:

   {
     "manifest_version": 3,
     "name": "My Extension",
     "version": "1.0",
     "icons": {
       "16": "icons/icon-light-16.png",
       "48": "icons/icon-light-48.png",
       "128": "icons/icon-light-128.png",
       "16": {
         "theme_light": "icons/icon-light-16.png",
         "theme_dark": "icons/icon-dark-16.png"
       },
       "48": {
         "theme_light": "icons/icon-light-48.png",
         "theme_dark": "icons/icon-dark-48.png"
       },
       "128": {
         "theme_light": "icons/icon-light-128.png",
         "theme_dark": "icons/icon-dark-128.png"
       }
     },
     "permissions": [
       "storage"
     ]
   }

My suggestion is to take the current icon, invert it so that the back and white and add it to the manifest to be used when browser there is dark.

Research direction
Create inverted versions of the current icons, then update the manifest.json to specify theme light and theme dark icons for each size.
