polars how to I read json lines from s3

Question

I am at a loss as to which polars interface I would pass s3_bytes from json lines file to get a dataframe

impl S3_Operation {
    pub async fn new(file: File) -> Self {
        let config = aws_config::load_from_env().await;
        let client = Client::new(&config);
        S3_Operation { client, file }
    }

    pub async fn download_object(&self) -> Cursor<Bytes> {
        let resp = self
            .client
            .get_object()
            .bucket(&self.file.bucket)
            .key(&self.file.key)
            .send()
            .await;

        let s3_bytes = resp.unwrap().body.collect().await.unwrap().into_bytes();

I want to get a polars dataframe at the end of day without moving s3_bytes to local storage. What am I missing here. JsonReader has no new fn while LazyJsonLineReader needs a path ...
