Messages Extension Mac-catalyst & macOS Sonoma

Hi according to the documentation we can have Message extensions in Mac Catalyst 14+, and that the MSStickerBrowserView is supported from Mac Catalyst 13.1+. But it doesn't seem possible to actually build an extension app, or Sticker extension, embedded in a Mac Catalyst app and have it appear in macOS messages.

Error:

iMessage Applications are not available when building for Mac Catalyst.

and

error: iMessage / Sticker Pack extensions are not available when building for Mac Catalyst.

With the announcement for macOS Sonoma that the Stickers will be available in Mac Messages, is this finally going to be possible?

If this isn't possible, why is there support for Mac Catalyst?

  • I should add, I have a working App for iOS/iPadOS with both a Messages Extension, and a Sticker extension. I'd like to at least make the Sticker extension available to macOS
