How do you test mac in app purchases?

I have an app that i uploaded to itunes connect. It was NOT built in xcode (it's unity) and it has In-App Purchasing.. How do you test in app purchases on a mac app? Don't you have to download the app from tha app store to be able to get IAP to work? There is no "test flight" in the mac side and unity does not crreate an xcode project for the mac like it does IOS.. so i am at a loss as to how to test this..

macOS IAP testing should be covered in this document, I believe:

And if you haven't already seen:

Note this is not an offer to troubleshoot unity

I have an EDUCATIONAL application only, it weighs nothing and is very basic: (on Unity 2020)
In my app (informative education), it includes five (5) scenes in total.
the first is free to access the other four (4) and buy them inside the application.
In other words, if the user wants to access the following scenes or levels, ...
access the first scene for free,
But to access the rest you must buy them with (IPA) IN APP PURCHASES.
I need this project only for DESKTOP MAC OS X.
(mac store only)
and I am using UNITY 2020.
There is any tutorial or some help please.
Thank you
