Apply VBA code to filtered rows

Hi all,

As you can see here ( https://docs.google.com/spreadsheet/...1E&pli=1#gid=0 ), I have a spreadsheet that was filtered manually, and now I want to apply some VBA code I made, only to the filtered rows, presented in the link. How can I do this?

By the way, the code goes like this (the range present on the code is an old one, I want to change that for the filtered rows on the previous link):

Sub SortRows()
    Dim RgToSort As Range
    Dim RgRow As Range
    Application.ScreenUpdating = False
    
    Set RgToSort = Range(Range("B1:C42"), Range("B1:C42").End(xlDown))
    
    For Each RgRow In RgToSort.Rows
        RgRow.Sort Key1:=Range(RgRow.Item(1).Address), Order1:=xlAscending, Orientation:=xlLeftToRight, OrderCustom:=1
    Next
    Application.ScreenUpdating = True
End Sub

Thanks in advance,
Joćo Fernandes
