how to generate jwt after authentication

const { Client, Account } = require('appwrite');

const client = new Client();
client
    .setEndpoint('xxxxxxxxxxxxxxxxxxxxx')
    .setProject('xxxxxxxxxxxxxxxxx');


const authenticateAndGenerateJWT = async (email, password) => {
    try {
        const account = new Account(client);

        // Step 1: Authenticate the user and create a session
        const session = await account.createEmailPasswordSession(email, password);
        console.log('Session created successfully:', session);

        // Step 2: Set the session token for subsequent requests
        client.setSession(session); // Use the session ID as the token


        // Step 3: Generate JWT
        const jwt = await account.createJWT();
        console.log('JWT created successfully:', jwt.jwt);

        return jwt.jwt; // Return the generated JWT
    } catch (error) {
        console.error('Error:', error.message);
        throw new Error('Failed to authenticate or create JWT.');
    }
};

Error: User (role: guests) missing scope (account)
Error: Failed to authenticate or create JWT.
