How do you upload a file to s3 and set the content-type?

I haven't tried it but did some searching. Maybe you can try this:

$file_handle = fopen('text.csv', 'r');

Storage::disk('s3')
    ->getDriver()
    ->put( 'text.csv',
           $file_handle,
           [
               'visibility' => 'public',
               'ContentType' => 'text/csv'
           ]
    );

Maybe not that exactly, but it looks possible.

This looks better:

Storage::disk('s3')->put($fileName, $file, [
    'visibility' => 'public',
    'mimetype' => 'text/csv'
]);

Thank you!
