How to know immediately when someone views my Whatsapp profile?

Is there a way to get notified immediately when someone views my WhatsApp profile?

Many of us think that is impossible. But my friend knows the exact second when I view her profile but she doesn’t tell me how. Even when I view her profile from a number which she doesn’t know, she knows immediately. I know modded Whatsapp like Gbwhatsapp show contact online. But she knows exactly when I am viewing her profile. How?
