Action Hook When Chunker Done Chunking

Hello,

I’m trying to run some custom functionality after the upload has finished. It would be cool if a custom action hook fired after all the chunks have uploaded and the attachment ID has been created. Currently, what I’m doing is:

add_filter( 'wp_prepare_attachment_for_js' function( $response ) {
	$chunk  = isset( $_REQUEST['chunk'] ) ? intval( $_REQUEST['chunk'] ) : 0;
	$chunks = isset( $_REQUEST['chunks'] ) ? intval( $_REQUEST['chunks'] ) : 0;
	if( ! $chunks || $chunk !== $chunks - 1 ) {
		return $response;
	}
	
	/* Custom functionality. */
} );

If there’s a better hook to run once the uploader has finished, please let me know!
