Beam Eye Tracker

Beam Eye Tracker

integrated camera
Hello, i ve been trying to setup the beam eye tracker, i have tried just about everything winthout succes for 1.5 hours, it just won t recognize the camera.
The error displayed "The selected webcam is currently incompatible,If it is currently in use by another application, go there and set a compatible webcam format or select Eyeware Camera as input device".
So the camera is working just fine in windows settings, i have granted all of the aprovment, in works in Lenovo Vantage (Laptop is Lenovo Legion 5i with 720 p camera), i have installed Opentrack selected Eye tracker from list...
In the windows settings does not display Eye tracker just the Opentrack (also granted camera acces)
Am I missing something, are the cameras from Lenovo laptops incompatible with Eye tracker?, it is a shame because from the reviews is a very good app to my needs.
