How to save temporary excel file to Sharepoint using VBA

I'm trying to modify the below VBA code to save the temporarily file on sharepoint. Below code creates a temporary excel file, which is attached to an email. Is there any way I can add a procedure to save the temporary file on sharepoint location. I was thinking that this part should be implemented somewhere in the below code.

***ActiveWorkbook.SaveAs Filename:= _
    "https://sap.sharepoint.com..." _
    , FileFormat:=xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False***




Sub EmailSelectedSheets()
    'Create email message with only Selected Worksheets attached

Dim SourceWB As Workbook
Dim DestinWB As Workbook
Dim OutlookApp As Object
Dim OutlookMessage As Object
Dim TempFileName As Variant
Dim ExternalLinks As Variant
Dim TempFilePath As String
Dim FileExtStr As String
Dim DefaultName As String
Dim UserAnswer As Long
Dim x As Long

'Optimize Code
  Application.ScreenUpdating = False
  Application.EnableEvents = False
  Application.DisplayAlerts = False

'Copy only selected sheets into new workbook
  Set SourceWB = ActiveWorkbook
  SourceWB.Windows(1).SelectedSheets.Copy
  Set DestinWB = ActiveWorkbook

'Check for macro code residing in
  If Val(Application.Version) >= 12 Then
    If SourceWB.FileFormat = 51 And SourceWB.HasVBProject = True Then
      UserAnswer = MsgBox("There was VBA code found in this xlsx file. "& _
        "If you proceed the VBA code will not be included in your email attachment. "& _
        "Do you wish to proceed?", vbYesNo, "VBA Code Found!")

    'Handle if user cancels
      If UserAnswer = vbNo Then
        DestinWB.Close SaveChanges:=False
        GoTo ExitSub
      End If

    End If
  End If

'Determine Temporary File Path
  TempFilePath = Environ$("temp") & "\"'Determine Default File Name for InputBox
  If SourceWB.Saved Then
    DefaultName = Left(SourceWB.Name, InStrRev(SourceWB.Name, ".") - 1)
  Else
    DefaultName = SourceWB.Name
  End If

'Determine File Extension
  If SourceWB.Saved = True Then
    FileExtStr = "Requirement List.xlsx"
  Else
    FileExtStr = "."
  End If

'Break External Links
  ExternalLinks = DestinWB.LinkSources(Type:=xlLinkTypeExcelLinks)

    'Loop Through each External Link in ActiveWorkbook and Break it
      On Error Resume Next
        For x = 1 To UBound(ExternalLinks)
          DestinWB.BreakLink Name:=ExternalLinks(x), Type:=xlLinkTypeExcelLinks
        Next x
      On Error GoTo 0


'Create Instance of Outlook
  On Error Resume Next
    Set OutlookApp = GetObject(Class:="Outlook.Application") 'Handles if Outlook is already open
  Err.Clear
    If OutlookApp Is Nothing Then Set OutlookApp = CreateObject(Class:="Outlook.Application") 'If not, open Outlook

    If Err.Number = 429 Then
      MsgBox "Outlook could not be found, aborting.", 16, "Outlook Not Found"
      GoTo ExitSub
    End If
  On Error GoTo 0



'Create a new email message
  Set OutlookMessage = OutlookApp.CreateItem(0)

'Create Outlook email with attachment
  On Error Resume Next
    With OutlookMessage
     .To = ""
     .CC = ""
     .BCC = ""
     .Subject = "REQUIREMENT LIST"
     .Body = "Please see attached list ."& vbNewLine & vbNewLine & ""
     .Attachments.Add TempFilePath & TempFileName & FileExtStr
     .Display
    End With
  On Error GoTo 0


'Close & Delete the temporary file
  DestinWB.Close SaveChanges:=False
  Kill TempFilePath & TempFileName & FileExtStr

'Clear Memory
  Set OutlookMessage = Nothing
  Set OutlookApp = Nothing
