MTGO install how to?

🍎macOS

Trying to install Magic: The Gathering online using heroic to run it on my mac. All I am able to download from them is a setup.exe and when I try to add game it builds the file paths but I can't find an executable and I'm worried it's not actually installing anything as most of the folders are empty. Is there a fix for this? I'm pretty new to Heroic and Wine in general so any help is appreciated.
