ReadyState4 equivalent for Chrome

I use the below code to paste into a browser tab in Chrome, which will then open into a CSV file. This works fine when I F8 through the code, but when I run the code, the file is slow to open and the code just runs through. My question - is there a ReadyState4 equivalent for Chrome, where I can delay the code until the new CSV file opens? Any other advice/options on how to do this would be appreciated. Have attached a workbook as well.

    Application.DisplayAlerts = False 
     
     
    Dim Count, FileSaveFolder As Long 
    Dim DogName, FormDownloadURL, FileSavePath, FName As String 
     
     
    Count = 2 
    FileSaveFolder = Sheet1.Cells(2, 3) 
    FileSavePath = Sheet1.Cells(3, 3) 
    DogName = Sheet2.Cells(Count, 1) 
    FormDownloadURL = Sheet2.Cells(Count, 4) 
    FName = ThisWorkbook.Name 
     
     
    Do While DogName <> "" 
         
         
        Shell ("C:\Program Files (x86)\Google\Chrome\Application\chrome.exe -url " & FormDownloadURL) 
         
         
        Do While ActiveWindow.Caption = "FormDownloader.xlsm" 
             
             
        Loop 
         
         
        Closefile = ActiveWindow.Caption 
        LastRow = Cells(Rows.Count, 1).End(xlUp).Row + 1 
        Cells(1, 18).Value = "DogName" 
        Cells(2, 18).Value = DogName 
        Range(Cells(2, 18), Cells(LastRow - 1, 18)).Select 
        Selection.FillDown 
        ActiveWorkbook.SaveAs Filename:=FileSavePath & FileSaveFolder & "\" & DogName & ".csv" 
        ActiveWindow.Close 
        Windows(FName).Activate 
        Sheet2.Select 
         
         
        Count = Count + 1 
        DogName = Sheet2.Cells(Count, 1) 
        FormDownloadURL = Sheet2.Cells(Count, 4) 
         
         
    Loop 
     
     
End Sub
