Very nice work. Would you also try and add generics to the uui-button story to allow us to have type-checking of props?

Example:

export default {...} as Meta<UUIButtonElement>;

const Template = Story<UUIButtonElement>...;

You only need to do so on the first story since all others inherit from that.
