Download zip file - blazor-server-side

Question

i have a zip folder in my wwwroot/files
how will i let the user download this file?
though about making a controller with something like this, but this is clearly wrong and it fails. It just does nothing even though it is reading the bytes and returning correctly
[HttpGet("DownloadOutput")]
public async Task<IActionResult> Invoice(string JobId)
{
string file = Directory.EnumerateFiles($"***PATH***\\{JobId}", "*.*",
SearchOption.AllDirectories)
.Where(n => Path.GetExtension(n) == ".zip").FirstOrDefault();
//converting file into bytes array
var dataBytes = System.IO.File.ReadAllBytes(file);
//adding bytes to memory stream
var dataStream = new MemoryStream(dataBytes);
HttpResponseMessage httpResponseMessage = new();
httpResponseMessage.Content = new StreamContent(dataStream);
httpResponseMessage.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment");
httpResponseMessage.Content.Headers.ContentDisposition.FileName = file;
httpResponseMessage.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/octet-stream");
return Ok(httpResponseMessage);
}
calling the file from my blazor code like this.
var result = await Http.GetAsync($"Inventer/DownloadOutput?jobId=JobId}");
