Linking back to a native app in OAuth flow. Invalid success URL. Expo react native, prebuild android

export const client = new Client()
    .setProject("12345*********")
    .setPlatform("com.thisis.myapp");
    

const doAuth = async () => {
        console.log(Linking.createURL(""));
        const account = new Account(client);

        const url = account.createOAuth2Token(
            OAuthProvider.Google,
            Linking.createURL("callback"),
            Linking.createURL("callback"),
            []
        );

        if (url) {
            console.log(url.href);

            const result = await WebBrowser.openAuthSessionAsync(
                url.href,
                Linking.createURL("callback")
            );

            console.log(result);
        }
    };```

When testing, if i remove the callback urls, a user is registered in appwrite but I am not redirected back to the app from appwrite.
`const url = account.createOAuth2Token(OAuthProvider.Google);`

> Missing redirect URL
> Your OAuth login flow is missing a proper redirect URL. Please check the OAuth docs and send request for new session with a valid callback URL.


Where am I going wrong here? I have seen similar posts but they seem to solve for web, not native apps. Not seeing any help with react native oauth in the docs.

ChatGPT suggests going to a section within appwrite where you can add authorized redirect URLS (would add "com.thisis.myapp"). This makes sense to me but that doesn't appear to be a setting.
