UIDropInteractionDelegate not working with Catalyst

I've added support for drag and drop by inheriting UITableViewDropDelegate from a table view in a view controller and implementing the appropriate methods to consume dragged data. This works fine between apps on iPad iOS 13 beta. I can drag URLs from Safari and bring them into the master view controller and they are inserted as rows in the table. However, when i build and laucnh the mac app via Catalyst, the same table view is no longer a drop target. If i drag URLs on desktop over the tableview the cursor doesn't change to a "+" and I can't drop on them here. Should this be working? Is there anything special I need to do to activate this feature on macOS?
