Calc : open a webpage on startup

Hi, I’m totally new to LO (used to Excel)

Can you explain me how to force to load an external webpage (say, Google) in the default browser at the launch of my LO sheet ?

Thanks in advance

That was my Excel boot code

Private Sub Workbook_Open()
Application.OnKey “~”, “MouseCursor”
ActiveSheet.GroupBoxes.Visible = False
ActiveWorkbook.FollowHyperlink Address:=“https://www.google.com
ActiveWorkbook.FollowHyperlink Address:=“https://www.bing.com
End
Sub
