Are Background Tasks supposed to work on Mac Catalyst?

I have an iOS application which uses both Silent Push Notifications and Background Tasks to keep the application up to date, both wake up the app even if it's killed and allow to run code on the background.

Now I've turned this app into a Mac Catalyst app. I've managed to get Push Notification working, but I'm only receiving them when the app is opened, the app doesn't wake up if it's closed.
Also, the Background Tasks don't work at all, the UIBackgroundRefreshStatus is always UIBackgroundRefreshStatusDenied.

Is there any further configuration needed to run background code on Mac Catalyst? or is it not possible at all?

Thanks.
