Entitlement checks in Unity3D

[MalboM]

Hello!
I'm trying to perform the entitlement check for my app with Unity3D since I had this problem when sending the game:

It appears that your app does not support entitlement checks to prevent unauthorized use of your content. Documentation on how to add entitlement checks can be found here: https://developer3.oculus.com/documentation/platform/latest/concepts/dg-core-content/#dg-cc-entitlem...


I'm trying these steps with Unity3D: https://developer3.oculus.com/documentation/platform/latest/concepts/pgsg-3-pw-platform-walkthrough/
it says Initialize the SDK using the App ID you got earlier. This is a one-line code change. For instance, if your App ID is 123456789012345, use the following: 

Core.Initialize("123456789012345");

but I don't know how to do this.

 can you help me?
thanks in advance
