How to take Manual backup of AWS elasticsearch to s3 bucket with indexname

i am taking the snapshot for manual backup inside s3 ,but inside the s3 bucket i am not getting snapshot with indices name. its something other than indices number.

i am using this command to take backup

curl -XPUT 'https://search-mb-production-app-bhbhhbh.us-west-2.es.amazonaws.com/_snapshot/my-snapshot-repo/28-11-2018'

and getting output in s3 bucket like
https://s3.console.aws.amazon.com/s3/buckets/elasticsearch-backup-indices/indices/ 0RZdYteiQLCbvGJacpC5IA

i want like
https://s3.console.aws.amazon.com/s3/buckets/elasticsearch-backup-indices/indices/alb-access.log-2018-11-28

access.log-2018-11-28 in index name in Elasticsearch
