PPX - Change view points in VR mode

Hello Community! I'm Yunjeong, CATIA IPC in Korea.
I appreciate getting a lot of information through the community.

I have one question from the customer regarding PPX (product perception experience) app.
They are one of the biggest A&D customer in Korea, current 3dexperience 2019x user and they are on a review to purchase VXP.

They want to change view points in VR environment(HMD) in PPX app.
as far as I know this can be done with camera(views) function in native apps, (live rendering, part design, assembly etc...) Like the picture below..


But this doesn't work in PPX. None in each versions on-premises/cloud -> maybe this is a bug?


Not necessarily this way, does anyone know how to change view points during VR(HMD) mode in PPX 2019x?

I've tried setting viewpoint variant and triggers, but the trigger didn't worked in VR mode.

(in upper versions, it can be done with activating "show viewpoints" and clicking cones on VR, but "show viewpoints" function isn't on 2019x)


Thank you 

Yunjeong
