Trigger 360 video to play when two cubes were added into basket.

Hi,

I wanted help to trigger 360 video to play when two cubes were added into the basket.
Form starting point player will move to the place I have added cubes when he places two cubes inside the basket that is nearby, automatically it should trigger(auto transition) to 360 video and user can watch the 360 video.

Thanks for the help in advance.
