What does `universal` property ([docs](https://developer.adobe.com/photoshop/uxp/ps_reference/interfaces/notificationevent/#optional-universal)) define when adding event to notificationListener?

Also docs now say [notification listener](https://developer.adobe.com/photoshop/uxp/ps_reference/modules/photoshopaction/#addnotificationlistener) accepts `NotificationEvent[]` as events, but then TypeScript complains, because for me only `string[]` works 😕 Can we get a versioned documentation?

I see @kerrishotts edited that docs page, so I’ll ping her
