File Download – Open file in a new Tab

I am using TelerikUpload control for file Upload. I am able to upload and download file without any issue. Currently for download when I click on download its downloading the file to Download folder. Instead of downloading, I want the file to be opened in a new browser tab without downloading. Any help on how this can be achieved. Please see my below code.

//Razor file
<script type="text/javascript">
    function downloadAttachment(filename, content, mimeType) {
        var blob = new Blob([content], { type: mimeType });
        var link = document.createElement('a');
        link.href = window.URL.createObjectURL(blob);        
        link.download = filename;
        link.click();
        window.URL.revokeObjectURL(link.href);
    }
</script>
<TelerikButton  @onclick="() => AttachmentDownload(item)">Download</TelerikButton>


//Razor.cs file
 private async Task AttachmentDownload(Attachment attachment)
 {
     var extension = Path.GetExtension(attachment.fileName);
     var mimeType = MimeTypeHelper.GetMimeType(extension);
     byte[] ByteArray = FileStorage.ReadFile(attachment.Path);

     if (ByteArray != null)
     {
         await JSRuntime.InvokeVoidAsync("downloadAttachment", attachment.fileName, ByteArray, mimeType);
     }           
 }
 
 public static string GetMimeType(string extension)
{
    switch (extension)
    {
        case ".pdf":
            return "application/pdf";
        case ".csv":
            return "text/csv";
        case ".txt":
            return "text/plain";
        default:
            return "application/octet-stream";
    }
}
