What are demo files to be deleted from Unity IAP Plugin?

Before I submit the app as a final version to the store should I clean up the UnityPurchasing folder and UnityChannel folder because these 2 folders is the one that we got after downloaded the IAP plugin right. They contains some demo files and we don't need to use them in the our game right. So could someone please suggest me like do we need to remove those and if yes what are the files to be remove.
Much appreciate!

 

The demo script files are very small in the final build, and should not cause concern. In the future we are considering placing them into a separate folder.

 

Thanks a lot for the reply!
