How to delete from SFDC Object in SSIS

How to delete from SFDC Object in SSIS

Hi there.  I have built out a suite of integrations using SSIS, SQL Server, and Devart for SFDC.  It is working well.

However, I need to clear out one SFDC object before I load it again.  I am the kind of guy who needs a worked example when I hit a brick wall, and I can't find one.

Can anyone help explain or show me how I do this?  I've put an SFDC Destination on my canvas, I've selected a connection manager, I've specified the mode as delete, and the object name.  I have zero idea what to do next :(

Cheers
Jo
