How to create list item Documet set in Folder?

Hi all.

We need to create list item - content type "Documet set" - on one of workflow steps in already existed item content type "Folder".. How can we do this?

When we create list item  - content type "Folder" - on one of workflow steps in already existed item content type "Folder" - it's working..

For "Documet set" we have result - created "Documet set" in root list.
