 - `inline`: When `true`, the inline modifier will be applied.
 - `name`: The name of the intended icon [in our library](/docs/design-icons--page).
 - `title`: If provided, a `title` element will be prepended to the icon source with the contents of this property. This will also set the `role` to `img` unless it is already specified. ([More info](https://css-tricks.com/accessible-svgs/#aa-example-1-standalone-icon-meaningful))
+- `muted`: When `true`, the icon will be displayed in a muted color.
+- `size`: The size to display the icon, taken from the `size.$icon` tokens.
 
 Additional SVG properties will be passed to the Twig template for the asset itself:
