Need help setting up oauth with github

const deepLink = new URL(makeRedirectUri({preferLocalhost: true}));
if (!deepLink.hostname) {
    deepLink.hostname = 'localhost';
}
const scheme = `${deepLink.protocol}//`; // e.g. 'exp://' or 'playground://'

// Start OAuth flow
const loginUrl = await account.createOAuth2Token(
    provider,
    `${deepLink}`,
    `${deepLink}`,
);

// Open loginUrl and listen for the scheme redirect
const result = await WebBrowser.openAuthSessionAsync(`${loginUrl}`, scheme);

// Extract credentials from OAuth redirect URL
const url = new URL(result.url);
const secret = url.searchParams.get('secret');
const userId = url.searchParams.get('userId');

// Create session with OAuth credentials
 const res = await account.createSession(userId, secret);
 console.log('Session created:', res);
// Redirect as needed
