Document Using useEffect with observables

[JRJurman]

Summary

It may or may not be obvious, but in order to have a useEffect "see" an observable, it needs to be called inside the useEffect function, e.g.

useEffect(() => {
	const { isSignedIn } = useGoogleOAuthSignedInStatus()
	if (!isSignedIn) {
		console.log('User Is Not Signed In... waiting...')
		return
	}
	console.log('User is signed in... creating events and hangout link...')
})

This should be formally documented with an example.

I wonder if we should have an additional function to call in useEffect that "watches" an observable for changes... Need a better example to showcase this 🤔
