"Cannot find 'GroupActivitySharingController' in scope" even when the documentation says that it is available on macCatalyst.

I would like to use the GroupActivitySharingController, but it seems it is not available for macCatalyst. On the iOS version, it works.

The documentation says that it should be available for catalyst: https://developer.apple.com/documentation/groupactivities/groupactivitysharingcontroller

Error message: "Cannot find 'GroupActivitySharingController' in scope"

Is there anything I have missed?

Thanks,
