Will users have to purchase my app twice?

Dear Apple & Community,

Sorry if this was asked already, but I couldn't find any concrete or up to date answers, this is my first time around.

I developed an App for both iOS and MacOS. They are on separate deploys (i.e. it is not cross compatible), but the same software nonetheless.

I would like that those who purchased it for iOS also get it for MacOS anad vice-versa. Is that possible? Is that out of the box or should I do anything extra in the App Store Connect or in the Deployment?

Thanks and best regards

Saif

Universal purchase lets people purchase your related iOS, iPadOS, macOS, tvOS, and visionOS apps together on the App Store. Your app will be available as a universal purchase after at least two platform versions are approved by App Store Review. Once this is done, you can’t disable universal purchase or remove a single platform version from the app record. For more information, see Create an app record > Add platforms and Distribute a Mac app built with Mac Catalyst.
