Environment: UE5/Windows/VS2022

Hi ,
So I have a gain slider Project and I’d like to use it as a .dll to load in a 3rd party plugin for unreal Engine
I’d like to know if such a thing is possible.
Here’s a beggining of an implemention I made :
Juce Project:

Unreal Engine Plug-in:

This work and correctly open a window displaying “Loaded Func From GainSliderLib”
But it have some issues because I need to add extern “C” for the dll loader of unreal engine to work so I can’t use any member function of GainSliderAudioProcessor if anyone already made an audio plugin in unreal engine I’d like some advices it would be much appreciated and I’d be grateful

Third party plugins are a burden but I managed to make it work.
There’s a serious lack of documentation and tutorial regarding this subject
