SharePoint workflow writes new elements in a dedicated list

Hello,

I've created a new  site content type named TCA based on the "document set" content type.

Every time when I create a new document set TCA I would like to have this triggered.
Means, every time when a new item (document set) has been created it should put the name
of it in a dedicated list library TCA_List.

How can I manage this?

BR
