Screen Reader

Message components use alert role that implicitly defines aria-live as "assertive" and aria-atomic as "true". Since any attribute is passed to the root element, attributes like aria-labelledby and aria-label can optionally be used as well.

Close element is a button with an aria-label that refers to the aria.close property of the locale API by default, you may usecloseButtonProps to customize the element and override the default aria-label.
