How to use hold/tap interactions in new Input System

Hi, I'm learning the new Input System and can't figure out how to use interactions. Everything is set, but I do not know how to code to do one thing with a single "tap" and another thing with "hold".

To be clear, I want to do something like if(SouthButton is held) {do "codeA"} else if(SouthButton is tapped) {do "codeB"}
