How to screen to a VR device connected later in Cloud XR?

I have built an AWS server that can use Cloud XR and prepared several Meta Quest2 as devices to connect to it.
When I connect to the server with Quest2, the video is displayed on it. If I then connect to the server with another Quest2, no video is displayed on it.

How do I stop the video on the first Quest2 and display the video on the later connected Quest2?

Thanks
