Authorization code grant flow

Hey y'all first time discord.js user. I'm using the latest version, going through the Authorization code grant flow in the guide. It's saying I should be returning

{
    "access_token": "an access token",
    "token_type": "Bearer",
    "expires_in": 604800,
    "refresh_token": "a refresh token",
    "scope": "identify"
}

{
    "access_token": "an access token",
    "token_type": "Bearer",
    "expires_in": 604800,
    "refresh_token": "a refresh token",
    "scope": "identify"
}

Except I don't get this back. My console is empty. I've tried changing response_type to code, and token, and neither of them return any information in my console. I'm not sure if i've missed a step but I've been staring at the guide for about an hour and a half to no avail. Here's my index.js just like the guide, for reference.

const { request } = require('undici');
const express = require('express');
const { clientId, clientSecret, port } = require('./config.json');

const app = express();

app.get('/', async ({ query }, response) => {
    const { code } = query;

    if (code) {
        try {
            const tokenResponseData = await request('https://discord.com/api/oauth2/token', {
                method: 'POST',
                body: new URLSearchParams({
                    client_id: clientId,
                    client_secret: clientSecret,
                    code,
                    grant_type: 'authorization_code',
                    redirect_uri: `http://localhost:${port}`,
                    scope: 'identify',
                }).toString(),
                headers: {
                    'Content-Type': 'application/x-www-form-urlencoded',
                },
            });

            const oauthData = await tokenResponseData.body.json();
            console.log(oauthData);
        } catch (error) {
            // NOTE: An unauthorized token will not throw an error
            // tokenResponseData.statusCode will be 401
            console.error(error);
        }
    }

    return response.sendFile('index.html', { root: '.' });
});



app.listen(port, () => console.log(`App listening at http://localhost:${port}`));

const { request } = require('undici');
const express = require('express');
const { clientId, clientSecret, port } = require('./config.json');

const app = express();

app.get('/', async ({ query }, response) => {
    const { code } = query;

    if (code) {
        try {
            const tokenResponseData = await request('https://discord.com/api/oauth2/token', {
                method: 'POST',
                body: new URLSearchParams({
                    client_id: clientId,
                    client_secret: clientSecret,
                    code,
                    grant_type: 'authorization_code',
                    redirect_uri: `http://localhost:${port}`,
                    scope: 'identify',
                }).toString(),
                headers: {
                    'Content-Type': 'application/x-www-form-urlencoded',
                },
            });

            const oauthData = await tokenResponseData.body.json();
            console.log(oauthData);
        } catch (error) {
            // NOTE: An unauthorized token will not throw an error
            // tokenResponseData.statusCode will be 401
            console.error(error);
        }
    }

    return response.sendFile('index.html', { root: '.' });
});



app.listen(port, () => console.log(`App listening at http://localhost:${port}`));

Well that’s for making bots right? All I’m trying to do is authorize users, not necessarily make a bot, it’s in a section of the discord.js so I thought I could come here for help
