Quick way to temporarily disable notifications in Plasma/KDE/Kubuntu?

Question

I'd like to be able to quickly disable and re-enable notifications in the KDE Plasma desktop (Kubuntu 19.04); essentially, a "focus" mode.

Previous (4+ years old) answers - Is it possible to temporarily disable notifications? - don't seem to apply, as the notify-osd process is not visible in my system process monitor.

Anyone have a simple method? I'm sure I could write a script or some such, but it seems like a feature that should be included in Kubuntu, and I'm wondering if I'm missing something.

I don't know if this is quick enough but ...

Kubuntu 18.10+ has kubuntu-notification-helper:

Kubuntu Notification Helper is a daemon that presents various notifications to the user. It uses the KDE Daemon system as a base and presents the notifications using the KDE Notification system. It also includes a System Settings module for configuring the daemon. Kubuntu Notification Helper is lightweight and fully integrated with KDE.

Current features include:
- Notifications for Apport crashes.
- Notifications for upgrade information, when available.
- Notifications for the availability restrictively-licensed packages.
- Notifications for when upgrades require a reboot to complete.
- All notifications can be hidden temporarily or permanently.

You can access this GUI via a terminal by running

kcmshell5 kcm_notificationhelper

The image below is from Kubuntu 19.04 with Plasma 5.16.2 (which is provided by the kubuntu-backports ppa.)

GUI for managing certain notifications

Alternatively, open System Settings and search for "Other notifications" to get the same GUI.
