theme
Enables browser extensions to update the browser theme.
To use this API, an extension must request the "theme" permission in its manifest.json file.
Note: When we set up a theme in a background file, we must declare the 'theme' permission and therefore we cannot use the theme function of the manifest, since it's not compatible.

theme.getCurrent()- Gets the current browser theme.
theme.update()- Updates the browser’s theme.
theme.reset()- Removes any theme updates made in a call to
