I want to transfer logs from nxlog to AWS S3 using python.

I would like to collect EC2 (Windows) logs in nxlog and forward them to S3 in AWS.
The knowledge is not circulating much on the Internet, and the following sites were barely available, so I am proceeding with it as a reference.
https://docs.nxlog.co/addons/amazon-s3.html
But I'm struggling because I'm a beginner at IT.

nxlog, python must be installed
1. Install Boto3 2.Edit nxlog.conf
3. Write the logic for the transfer in python and place it where nxlog can access it
4.nxlog Launch

I understand that this is the flow, but I don't understand procedure at all.
I don't know what code to write or where to put it.

If anyone knows a hint, could you please let me know?
