elasticsearch: On premise restore snapshot from aws s3

This could sound pretty straightforward. However, I've spent days looking in the web for a method where I can migrate snapshot from aws s3 to on premise elasticsearch cluster. All the docs I've found mentioning how to achieve this for es on cloud, where Kabana console is available. This doc for instance is an example. Can anyone advise me how can I achieve this? noting that: Snapshot taken, and a repo already exist within aws s3 bucket. 7 O.S: Centos 7
