PowerBI Report Embed from personal workspace in Local App

I have created a report with mock data in PowerBI (free version), which I would like to embed onto a local react application for testing purposes, but for some reason I cannot make it work.

My main problem is that I cannot find a way to get a valid access token.

First I tried to get the personal access token from the console (ctrl shift c -> console -> run powerBIAccessToken) but unfortunately the embed does not load.

Then I tried to get it through the public API, but when I use the group id and report id I get the error Calling group APIs not permitted for personal workspace.

This is my app.js code

import logo from './logo.svg';
import './App.css';
import { PowerBIEmbed } from 'powerbi-client-react';
import { models } from 'powerbi-client';

function App() {
    return (
        <div className="App">
            <header className="App-header">
                <img src={logo} className="App-logo" alt="logo" />
                <PowerBIEmbed
                    embedConfig={{
                        type: 'report',   // Supported types: report, dashboard, tile, visual and qna
                        id: process.env.REPORT_ID,
                        embedUrl: process.env.EMBED_URL,
                        accessToken: process.env.ACCESS_TOKEN,
                        tokenType: models.TokenType.Aad,
                        settings: {
                            panes: {
                                filters: {
                                    expanded: false,
                                    visible: true
                                }
                            },
                        }
                    }}

                    eventHandlers={
                        new Map([
                            ['loaded', function () { console.log('Report loaded'); }],
                            ['rendered', function () { console.log('Report rendered'); }],
                            ['error', function (event) { console.log(event.detail); }]
                        ])
                    }

                    cssClassName={"Embed-container"}

                    getEmbeddedComponent={(embeddedReport) => {
                        window.report = embeddedReport;
                    }}
                />
            </header>
        </div>
    );
}

export default App;
