useSignIn hook's qrCodeUri is always undefined

[tinaszheng]

What is the bug?
I'm using useSignIn to create a custom sign-in button. However, I'm seeing that the qrCodeUri returned by the hook is always undefined. I think I'm following the example here quite closely. Am I misunderstanding its usage?

How can it be reproduced? (optional)
I am on version "@farcaster/auth-kit": "^0.1.4",
This is a tiny snippet of my code, where this component is wrapped by a parent AuthKitProvider

const { qrCodeUri } = useSignIn({ onSuccess: () => undefined })
console.log(qrCodeUri)

and qrCodeUri is undefined on every render.

qrCodeUri seems to be updated to url in 0.2.2 and going through the code in <SigninButton> it seems that we need to first add these lines, then url will be available

auth-monorepo/packages/auth-kit/src/components/SignInButton/SignInButton.tsx

Lines 90 to 94 in 1bdd5e5

	useEffect(() => {
	if (!channelToken) {
	connect();
	}
	}, [channelToken, connect]);

Might be a bug though since it's not mentioned in the docs. This logic should probably be included in useSignIn() when it's first initiated
