What are the messages (Initializing UnityPurchasing via Codeless IAP)?

Question

Unity

I turned on the In-App Purchasing service, set the name and price id in the catalog, bumped the IAP Button buttons, and of course I set everything up for them (I installed the id, attached methods for successful and unsuccessful purchases), checked it works test ...
But constantly with startup pops up 2 messages of the following type

Initializing UnityPurchasing via Codeless IAP
UnityEngine.Purchasing.CodelessIAPStoreListener:InitializeCodelessPurchasingOnLoad () (at Assets/Plugins/UnityPurchasing/script/CodelessIAPStoreListener.cs:31)

UnityIAP Version: 2.2.7
UnityEngine.Purchasing.CodelessIAPStoreListener:InitializeCodelessPurchasingOnLoad () (at Assets/Plugins/UnityPurchasing/script/CodelessIAPStoreListener.cs:31)

And not as errors or warnings, just like a debug, why does it pop up, or is it normal and will it pop up all the time?
It's just normal for me when I run it and no messages (except for my debugs) are displayed...
