Do I have to save my data in a file before emailing??

[Fredericld]

Hi,

I have been working on the following code coming from the manual

(new InvoicesExport)->queue('invoices.xlsx')->chain([
    new NotifyUserOfCompletedExport(request()->user()),
]);

My export and notification run fine but I would like to know how I can pass the data from the export directly into the notification without having to go through the file creation?
