How to use S3 as storage for Loki logs?

Question

I am fairly new to Kubernetes, Helm and Loki.

I have deployed Loki-stack on my minikube cluster using Helm charts and I am trying to use S3 storage as storage for Loki logs.

I tried adding the following from the documentation of Loki to my custom chart and customizing it to my running S3 instance.

schema_config:
  configs:
  - from: 2020-05-15
    store: aws
    object_store: s3
    schema: v11
    index:
      prefix: loki_
storage_config:
  aws:
    bucketnames: bucket_name1, bucket_name2
    endpoint: s3.endpoint.com
    region: s3_region
    access_key_id: s3_access_key_id
    secret_access_key: s3_secret_access_key
    insecure: false
    sse_encryption: false
    http_config:
      idle_conn_timeout: 90s
      response_header_timeout: 0s
      insecure_skip_verify: false
    s3forcepathstyle: true

I made sure to customize the region, bucket names, endpoint, etc. But Loki is not storing any logs whatsoever there. I would like some help to show me what I might be missing or doing wrong?
