LIV on SteamVR not capturing with Avatar

I want to do a capture with my LIV avatar on SteamVR, but it is no longer supported.
In Japan, Sony released mocopi and I enjoy capturing with my avatar, but
OpenBrush does not support LIV, so I can't shoot composited images with my avatar.
I am very disappointed. I'm hoping for an improvement, but is there a problem with LIV?
Other apps are able to capture with avatars.
