Better example and API document

[minhchienwikipedia]

I'm having trouble with the example and the document. Does anyone have a best practice example with this lib? Basically, I want to select app -> set limit time -> config actions -> listen events.
I was tried an example, but too hard to make it work, I'm only can lock and unlock the app.

I understand that - I haven't had time to do this. Because of how the whole Screen Time APIs it is quite complicated. The best thing you can do currently is going by the TypeScript definitions which are pretty good.

PRs are welcome!
