Parent Class Blueprint Function

I have a ledge climbing system that is used by another Blueprint Character. I am trying to combine the Blueprint to my main Player Character. My SCharacter is able to shoot and use pickups and I want to merge the Ledge Climbing Blueprint to have my Character use the functions of the ledge climbing system without having to Merge the Blueprints together. I read you can Parent one blueprint to another and the Parent will inherit the Properties of the Child Blueprint. I have parented the Ledge Climbing System with my SCharacter but I don’t see anything happening after I parent my Ledge Climbing system to the Parent Scharacter. Do I need to add a script in my Construction Script or my Event Graph in my Parent Blueprint in order to use the Child Blueprint functions?

The PlayerPawn is the Spawn of the C++ class Scharacter

This is my Main Character C++ Class

This is the Main Player Character that uses the Scharacter C++ Class

This is the Ledge Climbing Blueprint I want to Combine

Here is the Blueprint Screen for main Character Using the SCharacter Class in the Blueprint Class Settings
