Aim assist on COD Black Ops Cold War

Hi all, newbie here. I would be grateful if any of you could give me some insight or input on my problems below: I've just purchased the Razer Raiju UE to play on my PS4. However, when I play FPS games i.e. COD modern warfare and COD Black Ops Cold War, it seems that there is no aim assist at all. I've played such games with the original PS4 controller and e-swap thrustmaster and the aim assist on both controllers work just fine. Anybody having similar issues with me? I'm just afraid that I purchased the "wrong" controller here
