Cannot configure web shortcuts in Okular in Manjaro XFCE

When I right click a word in Okular, there is an option to search for it in Google, Wikipedia, and other web services. However the option to “Configure Web Shortcuts” is not working (nothing happens when I click on it).

The terminal output is,

$ okular filename.pdf
kf.dbusaddons: Can not find 'kdeinit5' executable at  "/home/archisman/miniconda3/condabin:/home/archisman/.local/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl" "/usr/bin, /usr/bin"
"KLauncher could not be reached via D-Bus. Error when calling kdeinit_exec:\nThe name org.kde.klauncher5 was not provided by any .service files\n"

(This output occurs only when I click “Configure Web Shortcuts”).

Here is the output of inxi -Fazi

Okular is a kde application - the feature is most likely - provided by an optional dependency - if that is not the case you can try searching for it.

Make sure you have the files databases

$ sudo pacman -Fy

$ pacman -F kdeinit5 
extra/kinit 5.87.0-1 (kf5)
    usr/bin/kdeinit5

When you try to get such a specific application to work the way it was intended to may require the environment it was created for.

I get the following error when I try to do this after installing kinit.

kdeinit5: Got EXEC_NEW 'kcmshell5' from launcher.
kdeinit5: preparing to launch 'libkdeinit5_kcmshell5'
Could not open library 'libkdeinit5_kcmshell5'.
Cannot load library libkdeinit5_kcmshell5: (libkdeinit5_kcmshell5: cannot open shared object file: No such file or directory)
kdeinit5: PID 43729 terminated.

pacman -F kcmshell does not produce any output.

Edit: I verified that it works correctly in Linux Mint 20.2 XFCE edition. It would be great if someone can suggest a workaround for Manjaro.

A workaround is to install plasma-workspace, which installs a lot of dependencies. I don’t know which particular dependency of plasma-workspace does the job.
