 When you need access Context, you could use ``Notification.useNotification` to create a `contextHolder` and insert to corresponding DOM tree. Notification created by hooks will be able to access the context where `contextHolder` is inserted. Hook Notification has following methods: `info`, `success`, `warning`, `error`, `open`, `close`. For more usage demo, refer to [useToast](/en-US/components/toast#useToast_Hooks)
