HOW TO deploy simple NodeJS Backend to AWS [closed]

I am a beginner in backend. I am wondering how I can deploy my backend written in NodeJS and Express to AWS, so that my front end can send requests to the backend. I already have a web app hosted on GitHub. I used ChatGPT and it told me to use AWS Elastic Beanstalk for backend. I already configured eb in my local machine, but I do not know what to do next.

Suppose my backend is extremely simple that only contains (so we can focus solely on deployment):

app.get('', (req, res)=>{res.status(200).send("Hello World")})

Any help is appreciated. Thanks!
