locomotionExamples is missing in meta XR All-in-one sdk

Hello,

following this tutorial :

https://developer.oculus.com/documentation/unity/unity-isdk-create-locomotion-interactions/

i am blocked because i have to extract one prefab from a scene, but i can't find it (sorry for my bad english): locomotionExamples.

So impossible to do this step :

"Adding Locomotion Interactors for Controllers"

I have the last version of

meta XR All-in-one sdk  and

meta XR interaction sdk Ovr integration

if someone can help me please ?
