Is it possible to stream a file from a URL ? ex: Amazon S3 ?

I tried to do:

stream= File.stream!(public_s3_file_path)

I got error, although the file is there and public:

** (File.Error) could not stream "filepath...": no such file or directory
    (elixir) lib/file/stream.ex:78: anonymous fn/2 in Enumerable.File.Stream.reduce/3
    (elixir) lib/stream.ex:1240: anonymous fn/5 in Stream.resource/3

    Args: [#Function<0.55381211/2 in Task.Supervisor.build_stream/5>]

So, how would I stream it?
