Excel VBA - Creating calendar item with Description and reminder

Hi. How do I update the following code so that I can include a description and set a reminder to an hour before

Sub CreateCalendarItem(olkApp As Outlook.Application, _
            strSubject As String, strDate As String, _
            strTime As String)
   Dim olkAppt As Outlook.AppointmentItem
   Dim dte As Date
   
   ' Must add Outlook to references for this to work
   dte = CDate(strDate & " " & strTime)
   
   With olkApp
      Set olkAppt = .CreateItem(Outlook.OlItemType.olAppointmentItem)
      With olkAppt
         .Start = dte
         .Subject = strSubject
         .ReminderSet = False
         olkAppt.Save
      End With
   End With
   
   ' Clean up.
   Set olkAppt = Nothing
End Sub
