I tried screen sharing of smartphone with "Oculus Quest"

Oculus Quest arrived the day after the release date
I'm trying to accept a cast request from the Oculus app on the Oculus Quest side.Both are icons with the text "cast", but they are "mirroring source", "mirroring destination", and "permit mirroring".
The image on the left is captured by Oculus Quest, and the image on the right is captured by Mate 20 Pro. By comparison, you can see that the angle of view was not wide, but the 1: 1 image was just cropped to 2: 1.I wanted you to return a happy feeling
