Action RPG Inventory System

Hello, I am trying to combine this package with their Multiplayer TopDown Kit. I have closely followed the specific video and the generic integration video, but both videos show a SET box immediately connected to the “Inventory Manager Component”. Yet the current version does not contain this SET box and every “set” option that I have tried off of the “Inventory Manager Component” pin does not produce a working combination. There has been no response from the creator, so I need to reach out to those who have already integrated it to know what must I connect after the “Inventory Manager Component” in the BPs like Inventory Layout and Container_Slot? Thanks in advance for any information.
