How to correctly group an SoftwareApplication which is available in many stores?

[MTRNord]

Hi I am currently trying to SEO tag a website for an App which has Apps for Android, iOS, Linux, Web, and macOS. This means I have various different download URLs per platform, as they all do have their own stores.

What is the correct way to do this? My current approach was kind of based upon Google's suggestions and looks like this:

<script type="application/ld+json">
    {
        "@context": "https://schema.org",
        "@type": "SoftwareApplication",
        "name": "Fluffychat",
        "applicationCategory": "CommunicationApplication",
        "countriesNotSupported": "fr",
        "operatingSystem": "ANDROID, IOS, WEB, LINUX, MACOS",
        "releaseNotes": "https://gitlab.com/famedly/fluffychat/-/blob/main/CHANGELOG.md",
        "screenshot": "https://gitlab.com/famedly/fluffychat/-/raw/main/docs/screenshots/mobile.png",
        "softwareHelp": "https://gitlab.com/famedly/fluffychat/-/wikis/FAQ",
        "author": {
            "@type": "Person",
            "callSign": "KrilleFear"
        },
        "license": "https://gitlab.com/famedly/fluffychat/-/blob/main/LICENSE",
        "offers": {
            "@type": "Offer",
            "price": "0",
            "priceCurrency": "USD"
        },
        "aggregateRating": {
            "@type": "AggregateRating",
            "ratingValue": "4.5",
            "ratingCount": "133"
        }
    }
</script>

However, that leads to not be able to add a download url and some other fields. So I wonder what the correct way of doing this is.

Sometimes in Schema.org you will find you need to repeat things because the details on a Thing, truly make each one of them a bit different. This also has the benefit of being less ambiguous for each Thing. In this case, each OS application, of which I count you have 4?
So... Just make 4 of those for each OS version, instead of trying to combine all the operating systems. I get that it's probably 1 release in your mind, but in reality think of it as 4 releases, one for each OS, each one having a particular rating against that OS or App marketplace, as well as maybe specific release notes addressing issues or new features per OS, if you want.
