how to use private S3 buckets as update source

[truar117]

Hello,

I publish my App in a private bucket. The reading of this bucket should be restricted by an technical IAM user that has read rights to this bucket. Unfortunately the update-electron-app doesn't support the using of accesskey and access-secret, as provided in the publisher configuration. The access could also be handled by aws4 and passing the request-params, but I doesn't find a solution to pass the request-options to the update-electron-app call? Thank You for any help or hint/solution
