You can follow the issues mentioned in the lighthouse one by one.
React and Virtual DOM suffer from slow performance. Use a faster JS framework like Solid-js. https://solidjs.com/
Watch this video for general performance issues: https://www.youtube.com/watch?v=Lh9q3h2khlc
Use this website to know the cost of your dependencies: https://bundlephobia.com/package/react-dom@17.0.2
Note that there's a big difference if you run these tests on dev mode or production mode.
I assume that if you'll build it in production mode and deploy it to netlify or another hosting provider, you'll see different numbers.
