Is it possible to implement Mac App Store in-app purchases in LiveCode?

[kee nethery]

And if it is possible to do in-app purchases in macOS apps, are there instructions or sample code anywhere? It appears to me that the Apple documentation assumes I am using Swift and have imported a set of libraries that are called via Swift. 

Is there a sample stack somewhere for Mac apps?

Has someone created a library I can use?

Thanks,
