How to change UE4 interface input type

ive got an interaction interface that is called whenever it hits a valid actor but when i go to the interfact function it asks for an interaction interface as a target instead of an object

i am not sure … its the right node?
take a look at this quick video about interface WTF Is? Blueprint Interface - YouTube

i managed to fix it by going to class settings and removing the interface and it allowed me to call it right i dont know why this is a thing
