upload multiple files with UploadDropzone

how can I upload multiple images thru this component? I saw there's an option on the component that says

 config={{
            appendOnPaste: true,
          }}

 config={{
            appendOnPaste: true,
          }}

 config={{
            appendOnPaste: true,
          }}

 config={{
            appendOnPaste: true,
          }}

but not sure if it does what I'm looking for
