How to load the values of custom console variables from an .ini file?

I’ve created a console variable in C++ code. As follows:

void AGuideCine::BeginPlay()
{
    Super::BeginPlay();

    IConsoleManager::Get().RegisterConsoleVariable(TEXT("r.GuideAudioFF"),
        0,
        TEXT("Decides whether to fast forward(FF) when the Guide is playing audio.\n")
        TEXT("  0: FF off\n")
        TEXT("  1: FF on\n"),
        ECVF_Scalability | ECVF_RenderThreadSafe);
    ConsoleVarGuideAudioFF = IConsoleManager::Get().FindConsoleVariable(TEXT("r.GuideAudioFF"));
}

However, I don’t know how to load the console variable value from an .ini file, which I want to specify as the default value.
