The ability to record Nreal screens to share content with others

It is said to have the ability to record Nreal screens to share content with others.
After switching to MR mode, it is explained that if you press and hold the touch interface of the mobile, a shooting option appears. Is this currently available? No option selection screen appears.

I would like to share not only the AR App developed with Unity, but also multi-explorer and other operation screens in MR mode.
