Call one Gameplay Function Externally in UE5 using C++

I need assistance with my Unreal Engine 5 reverse project. I want to call a gameplay-related function from UFunctions externally in C++. Making one function call work will be sufficient for completing this task. The primary purpose is to trigger in-game function. Using memory offsets. ( Using a SDK dumper is recommended to see the client sided game structure )

Key requirements:
- Understanding of Unreal Engine 5's architecture.
- Proficiency in C++ programming.
- Experience with UFunctions and external function calls. ( using GObjects, GNames, GWorld, ProcessEvent )
- Good understanding of Unreal Engine 5 API calls.
- Ability to debug Unreal Engine 5 gameplay functions.
- Memory management / ASM

Currently, I have a dumped SDK from the game's codebase. I can call any function injecting a DLL with no problem ( internal ). But i want to understand how I can replicate the behavior externally, triggering functions, without the need of injecting a dll.

The function call should trigger a interaction-related event in-game. I only need a POC that triggers 1 function for this project, so i can understand how it can work.

If you already know how to do this, and can show it to me, and i get it to work with 1 function - its all good and job complete.
