filename for document

[fabianm1705]

Hello, I have a template with which I send a pdf document but I don't know if there is an option to name the file. Because otherwise it arrives fine but as null.pdf

return WhatsAppTemplate::create() ->name('envio_factura') ->language('es_AR') ->header(Component::document(url('pdf/file.pdf'))) ->to($notifiable->cell_phone);
