weather applet, network applet in MATE Desktop

[Gottfried]

Hi,
I installed guix with MATE desktop the first time.

I was wondering, why only few programs were installed. I have great 
trouble to add new programs and need a lot of advice.

e.g. no printer, scanner, no weather applet, network applet and other 
applets  in the quick launch bar available.

How can I install a weather applet (to show the weather conditions in my 
quick lanch bar) and a network applet to show download and upload 
traffic, which is available in MATE desktop, because I used MATE in 
other distros like EndeavourOS. Or is it only available in MATE 1,26, 
the newest MATE?
