Add-on SVG toolbar icon: How to fit the color scheme of the current theme

Thank you! It works fine!
Here is my manifest:

"browser_action": {
  "browser_style": true,
  "default_icon": "icons/icon.svg",
  "theme_icons": [
    {
      "light": "icons/light-icon.svg",
      "dark": "icons/icon.svg",
      "size": 16
    },
    {
      "light": "icons/light-icon.svg",
      "dark": "icons/icon.svg",
      "size": 32
    }
  ],
  ...
}
