you can't see the camera and it's in the game

once there was a camera or a camera added in minecraft pe, but not fully implanted, and then it was removed in 0.16.0. Then in version 1.12 the camera or camera was added again, but only in version 1.12. He writes the command to get this thing and doesn't go, and I'm in an experimental world. I don't know if it's only on Android.

Will this item be available in version 1.16 or in the next possible version 1.17?
