Error loading QML file: file:///home/[my_username]/.local/share/plasma/plasmoids/org.kde.plasma.notifications/contents/ui/main.qml:29:1: module "org.kde.plasma.private.notifications" version 1.0 is not installed

This is talked about in the Arch Linux Forum

Running Plasma 5.17.4-1

I don't know if it is the right place for this, but it would be nice if the notification icon turns red (by example) when there are unread notifications.

It will catch attention if you went away of your desk :)

I would like to see a panel/notification widget that would use the full screen height. Something like the (almost useless) Windows Action Center, but where one could put whatever widgets he wants.

I've tried to use a regular panel on the right side of screen with auto-hide but it's not usable because on every touch on the right side it shows up.

I think the solution would really be a button that would change the visibility of that panel on click (something like the activities button does).

The intention is that for notifications, clip areas, updates, (or whatever plasmoid/widget wanted), one could easily make use of the full screen height. :)

By the "Full Notifications" i was thinking this plasmoid would do that :)

Just got the update to 5.16 and wanted to try the new notification system but after uninstalling the plasmoid I no longer get notifications.

And my system tray displays only full notifications.
Please help.

Expected Result: The notification applet should've open and everything works perfectly

Real Result: It opens and show an error saying that it couldn't load Full Notification.
Here is the log:

I've already installed plasma-browser-integration, but it still doesn't work and it shows the same error.
