shadow is not visible in oculus quest.

Hi , i'm trying to build from unity to oculus quest. I have couple of problems :

1. when build and run on oculus , there's no shadow . It's just simple scene with couple of objects. I can see the shadow in unity, but when run inside oculus , the shadow is just dissapeared.

2. How to build and run from unity and see the feedback in unity . I saw some videos on youtube, when the 'play' button (on top of unity) is pressed , the app is run in oculus and the view feedback is sent back to unity, so i can see what someone see inside the oculus headset. I'm using unity latest version on mac/osx catalina.

Does anyone can help ?

Thanks
Andi
