Converting my apps from Delphi Seatle to Berlin need help with the new MessageDialog setup

I am looking for an example on how to setup TDialogService.MessageDialog

I need to convert the fmx messagedlg to messagedialog since I am getting this:[DCC Warning] MainFormU.pas(169): W1000 Symbol 'MessageDlg' is deprecated: 'Use FMX.DialogService methods'

Thanks
