How can I access AR experience generated from CREO if I need this AR in Studio?

How can I get access to my AR experience created by CREO Parametric for upgrade it by my local Vuforia Studio? After CREO I have the ThingMark only, no URL or ZIP import file of AR experience. I need to follow created AR adding to it different widgets and augmentation  by Studio, but cannot do it because don't know how can I get my AR from PTC Experience Service.
