adding cors for ?proxied content

[rosolinol]

Hello,

any idea how to enable "Access-Control-Allow-Origin": '*', for ?proxied content ?! i've add "Access-Control-Allow-Origin": '*', almost everywhere but still when i try to access content from url?proxied it still cannot access it from another website

async function proxiedDownload(downloadUrl) {
    console.info(`ProxyDownload -> ${downloadUrl}`);
    const remoteResp = await fetch(downloadUrl);
    let option = {
        status: 200, 
        headers: {
        "Access-Control-Allow-Origin": '*',
        }
    };
    let {
        readable,
        writable
    } = new TransformStream();
    remoteResp.body.pipeTo(writable);
    return new Response(readable, remoteResp, option);
}

is not working... help?

Thanks
