Issue

The documentation gives instructions on how to register and then unregister events, but the provided code example isn't valid and doesn't work even in the most basic sense.

the eventContext.context provided as a param in the Word.run has a type mismatch and is not working.

trying to work around the issue by casting doesn't resolve the issue and just leads to the Word.run to throw

also the example provided doesn't take into account the possibility that eventContext could potentially be undefined or null, which is also wrong but easily fixed by adding some if(eventContext) where needed.

Questions

Is there another approved way of registering/unregistering events that I haven't found in the documentation?

Is there other ways to get notified of document changes that do not rely on the events?
