Question Change to Face Recognition

Hi!
I have an app with 2 scenes. In one I have an Image Marker with a button and it is using back camera from my phone. When I press that button it should open another scene where I have a face mask for face recognition and it should open front camera.
But when I enter in the second scene it is opening something strange, but not any camera.

Any idea what I can do ?
I need to change camera manually?

Thank you!
