how to use AppState in a functional component and hooks? Necessary or am I using useEffect incorrectly?

I want to be able to run a function when a user goes into the app. I thought useEffect would already do something like this, say if I choose to change my phone's Clipboard (copy different texts from another app). But its not rerendering the component.

const [clipped, setClipboard] = useState();
const [appView, setAppView] = useState(AppState.currentState);

const getFromClipboard = useCallback(() => {
  Clipboard.getString().then(content => {
    console.log('content:', content)
    setClipboard(content);
  });

}, [clipped]);

useEffect(() => {
  getFromClipboard();
}, [getFromClipboard, clipped, appView]);

I would assume that every time I copy a new text from a different app, into my clipboard, and then I go back to this app, because the state changed in clipped, it will rerender the useEffect? Unfortunately, its not calling the console log after first initial load of the component.

I stumbled across AppState, and thought I might be able to give this a shot, but not sure how to set this up with useEffect?
