How to Duplicate Files from one Form Page into another Form Page

Hi All, question please.

I want to "copy" or "duplicating" some attachment file(s) inside default feature from Creatio.

Based on document here :
https://academy.creatio.com/docs/user/bpm_tools/process_elements_reference/system_actions/process_file/process_file_element

We need to find source file with “Attachments and notes of the object”, but I can not find "Attachments and notes of the object" in my environment (Business Process).

Need advice please, thank you.

Note : Studio Creatio version : 8.3.4.2753
