Help Setting up S3 Bucket

I need some help setting up an AWS S3 bucket for use as a media source in MODX.

I installed the newest plugin for MODX GitHub - modxcms/aws-s3-media-source. I am confident everything on MODX is ready for me to add the media source. Additionally I have the keys from AWS ready to enter in the media source setup.

But my questions are really about setting up the bucket correctly. I know I will need to make changes to the properties, permission, and possibly access points for the bucket.

Does anybody know of a tutorial or information on configuring the bucket?

Thanks in advance.
