Nik Collection Plugin for Affinity Missing

Urgend request to the Nik guys: please add a plugin for Affinity Photo + Designer + Publisher. Currently it is even not possible to add it manually to the list. Please take into consideration, that a AppStore and Download version of Affinity products exist for Mac. The AppStore one must run due to AppStore restrictions sandboxed, the other one not. That cases problems also trying to add Nik collection from within e.g. Affinity Photo. Please don't forget to add native Affinity Photo support for the .afphoto files.
