Use PdfEmbeddingFonts in Fast Report

I use a code example to create a report with FastReport in my Blazor app. Everything works fine but when I export the report to PDF the fonts I use are not there. How do I embed Fonts in my code?

This is the code I use.

 FastReport.Utils.Config.WebMode = true; Report rep = new Report(); string path = Path.Combine("Reports", reportLayoutName); rep.Load(path); rep.SetParameterValue("Etichetta", model.Etichetta); rep.SetParameterValue("Company", model.Company); rep.SetParameterValue("Pratica", model.Pratica); rep.RegisterData(model.Fatture, "dataModel"); if (rep.Report.Prepare()) {    PDFSimpleExport pdfExport = new PDFSimpleExport();    pdfExport.ShowProgress = false;    pdfExport.Subject = "";    pdfExport.Title = "";    MemoryStream ms = new MemoryStream();    rep.Report.Export(pdfExport, ms);    rep.Dispose();    ms.Position = 0;    return File(ms, "application/pdf", reportName);  }

I can't figure out how to add fonts to the PDF.Thank you
