Upload file to s3 with tag provided

Thanks for great lib and community.

I’m trying to attach tag to a file while uploading on s3,
from documentation it seems that upload_options param of storage object, or upload_options as plugin should work great.
But neither
Shrine.plugin(:upload_options, { tagging: "my_tag=1" })

    Shrine.storages = {
      cache: Shrine::Storage::S3.new(
      store: Shrine::Storage::S3.new(
        access_key_id: KEY,
        secret_access_key: SECRET,
        bucket: BUCKET,
        region: REGION,
        upload_options: { tagging: "mytag=1" }

worked for me.

s3 lib, put_object method has param called tagging which I assumed should have been forwarded from upload_options

Any hints?
Am I missing something?

Thanks in advance,
