The requireInteraction read-only property of the Notification interface returns a boolean value indicating that a notification should remain active until the user clicks or dismisses it, rather than closing automatically.
Note: This can be set when the notification is first created by setting the requireInteraction option to true in the options object of the Notification() constructor.
