I tried to install the Network Manager in the following way:

Yast > System > Network Settings > Global Options > Network Setup Method

...

( Wicked Service | Network Manager | Network Services Disabled )

After selecting "Network Manager" and clicking "ok", the following warning message appeared in a small pop-up window:

Applet needed NetworkManager is controlled by desktop applet (KDE plasma widget and nm-applet for GNOME). Be sure it's running and if not, start it manually.

How and where can I get the KDE plasma widget mentioned in the previous message and how do I install and start it?

How do I program the Network Manager?

Thanks in advance for your help?

I believe the applet is plasma-nm5

you can program the NetworkManager using nmcli which is included in NetworkManager or add nmtui via NetworkManager-tui and use it.

There is also nmcli, for example to setup a static ipv4 address for eth0: nmcli con mod eth0 ipv4.method manual nmcli con mod eth0 ipv4.address 10.0.0.90/24 nmcli con mod eth0 ipv4.gateway 10.0.0.1 nmcli con mod eth0 ipv4.dns-search mydomain.co.nz nmcli con mod eth0 ipv4.dns "10.0.0.9,8.8.8.8" nmcli con mod eth0 connection.autoconnect yes nmcli con up eth0 ip address ip route
