Custom UI uses the ability to hide videos of non-video participants

Hi,
We now use component View, customize background, resize video and shared location, but can’t find Settings to hide non-video participant videos.
If the client View in the picture can hide non-video participants, can’t our custom layout be used?

We made some adjustments, but we couldn’t get the client View full screen into our own element, so we added something outside.

Your page is full screen, I want to change its size, not full screen, we need to make it like this, there is a background picture behind, so do you support hiding non-video participants after the change?
