-`aria-live` causes screen readers to announce the content of the toast when it is presented. However, since the attribute is set to `'polite'`, screen readers generally do not interrupt the current task. Developers can customize this behavior by using the `htmlAttributes` property to set `aria-live` to `'assertive'`. This will cause screen readers to immediately notify the user when a toast is presented, potentially interrupting any previous updates.

 `aria-atomic="true"` is set to ensure that the entire toast is announced as a single unit. This is useful when dynamically updating the content of the toast as it prevents screen readers from announcing only the content that has changed.
