How to display speed ethernet indication in linux kde?

Question

linux

Given: mageia linux 7, KDE, network applet net_applet.
Required: indication of the current speed of the ethernet link, preferably somewhere in the tray somehow with an icon or stupid numbers. For example, right now I'm only looking at this in the terminal:

[[email protected] ~]$ cat /sys/class/net/enp5s0/speed
1000

Actually, I see a solution in the form of a widget to display the connection speed (10/100/1000), but I did not find a working widget. There is a tail widget that should display the last lines of the file, but it just doesn't work, it doesn't show anything.
Just the numbers 100/1000 in the tray would be enough for me to quickly change in accordance with the connection.
I’m even ready to somehow participate in the development / completion of net_applet, but I haven’t found anywhere, not only the source code, but also some place or person to whom to ask such a question.
For the developer, this (as far as I can guess) is not at all a problem - in addition to the "no network", "connected to the network" icon, add more options "connected at 100Mbps", "connected at 1Gbps", because. this applet has in the settings which interface to watch, respectively, can get the current speed (no special rights are needed for this).

Help me understand where I should go next, or write some kind of crutch.

This might work (I haven't tried it myself).

Here is the source of the drakx-net package from mageia 7: sophie.zarb.org/rpms/1a149924e962ca57b572b11802f8f...
There is a URL in the spec file from which the sources are taken: gitweb.mageia.org/software/drakx-net
