Support PUT operation for 2-phase attachment upload

[ilovepb]

hi all,

i appreciate the frictionless devex on uploading attachments to chatkit.

i want to move from using direct uploads to the 2 phase approach, but i currently use S3 as my object store. I think S3 only supports PUT operations for presigned upload URLs unfortunately.

https://docs.aws.amazon.com/AmazonS3/latest/userguide/PresignedUrlUploadObject.html

any big limitations on being able to support PUT upload URLs?

This is something we're working on supporting! I'll post here once we've updated the interface 👍
