BeginPlay() and Tick() in pawn not firing...

Hey, I just tried to make Discord Game SDK, but unfortunately when I try to make it.
I came around the issue that the events: Tick & BeginPlay don’t fire. (tested it with printf(); method)

Please help me out.

#include <stdio.h>
printf("") ???

#include “Engine/Engine.h”
GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Red, L"");
