AWS s3 add User-Defined Metadata without storing `x-amz-meta-`

Question

Im using AWS s3 to store files, i need to add User-Defined Metadata

"Content-Disposition": attachment;filename=filename.txt when uploading the file/object to aws so i would be able to download it, when uploading with javascript i need to add x-amz-meta-content-disposition, now in s3 the metadate Key is stored as x-amz-meta-content-disposition but the file is not downloding, when i remove manually in AWS console the first part x-amz-meta- and only leave content-disposition then im able to download.

Now my question is: how can i upload the file using javascript and x-amz-meta- should be removed and just be "Content-Disposition": attachment;filename=filename.txt
