How to copy a dynamic range with VBA and paste in another workbook?

Friends, I am trying to copy a range of cells that encompass two columns and paste it into another workbook.
The range will/could be added to at any given time so the code has to be able to go to the last cell with data. Here is the code I have so far but I cannot get it to work. Any ideas would be helpful!

Sub Find_Performance_Log()
    Dim FindString As String
    Dim Comment As String
    Dim Rng As Range
    Application.ScreenUpdating = True
    'Comment =
    Worksheets("Submit Comment").Range("C21").Value = "Comment Date"
    Worksheets("Submit Comment").Range("D21").Value = "Comment"
    Worksheets("Submit Comment").Range("E21").Value = "Executive"
    
    FindString = Sheets("Submit Comment").Range("B14").Value
    If Trim(FindString) <> "" Then
        With Sheets("Employees").Range("A:A")
            Set Rng = .Find(What:=FindString, _
                            After:=.Cells(.Cells.Count), _
                            LookIn:=xlValues, _
                            LookAt:=xlWhole, _
                            SearchOrder:=xlByRows, _
                            SearchDirection:=xlNext, _
                            MatchCase:=False)
            If Not Rng Is Nothing Then
                Application.Goto Rng, True
                ActiveCell.Offset(1, 1).Select
                'ActiveCell.Name = Comment
                ActiveCell.End(xlDown).End(xlToRight).Copy
                Worksheets("Submit Comment").Activate
                Worksheets("Submit Comment").Range("C22").Paste
               ' ActiveCell.EntireRow.Offset(1, 0).Insert
               ' ActiveCell.Offset = Now()
               ' ActiveCell.Offset(0, 1) = Sheets("Submit Comment").Range("D6").Value
               ' Worksheets("Submit Comment").Activate
               ' MsgBox "Your comment has been submitted."
               ' Range("D6").ClearContents
               ' Workbooks("Performance Log.xlsm").Save
            Else
                MsgBox "No Records found on associate"
            End If
        End With
    End If
End Sub
