How to add Button Presses for C++?

Im trying to get button presses to work and I cant seem to figure out how they work based off of the starter content.

Im tracing the Jump and MoveRight premade functionality in the 2D Platformer Template. The only thing I understood from it is that the button presses are automatically detected from the engine, but I have no clue as to how to actually get them to do something in game.

TLDR: How do I link controller button presses link to a C++ method within my Character.cpp?
