Feature Request: Add a Theme command/action to set the theme from your smart home

It would be nice to have the ability to set the theme of the browser externally. For example - when I set my office theme in Home Assistant, all of the lights change color, my wallpaper changes, and it would be nice if the theme of the browser changed too! Either the accent color could change, or you could set the theme by name. Accent color change would give more customizability.
