Described a REST client for file upload

@HttpExchange("${google-drive.url}")
public interface GDriveClient {

    @PostExchange("/upload/drive/v3/files")
    ResponseEntity<GDataOutput> uploadFile(@RequestHeader("Authorization") String authorization,
                                           @RequestBody byte[] data);
}

It works, but the file is downloaded to the root and with a fixed name Untitled

I want it to download to a specific folder and have a name generated in the application

One example shows the following transmission format

curl -X POST -H "Authorization: Bearer ${r}" 
    -F "metadata={name :'test.txt'};type=application/json;charset=UTF-8" 
    -F "[email protected];type=text/plain" 
    https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart

But I don’t understand how I can transfer such a format.

Who has encountered this, tell me how I can transfer metainformation
