-`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.

This will cause screen readers to immediately notify the user when a toast is presented, potentially interrupting any previous updates.
