switch (e.detail.theme) {
case 'dark':

method is more than likely all you'll need. Here's a list of what each method in the module does.
// 1. fetch preferred theme
// 2. dispatch result via 'colorSchemeUpdated'
theme.get()
// 1. runs `get()`
// 2. adds `colorSchemeUpdated` event listener to window
theme.watch()
// removes `colorSchemeUpdated` event listener from window
theme.destroy()
