I was going through the application list under Plasma and found that these two apps don’t look too familiar. Are they required and pre-installed by the system? If so, what’s their function? If not, how to find out how they got installed and how to completely remove them without breaking any dependencies? Thanks a lot!

Those are not installed by default. Electron is a dependency of electron-based applications.
You can remove them with:
sudo pacman -R electron26 electron28
You may find that you still have applications installed that need them.

Try pactree -r X ( replace X with the name of a package) to see what is dependent on X in your system.
Example:
$ pactree -r pacman
pacman
├─arch-audit
├─arch-install-scripts
├─archlinux-keyring
│ ├─base
│ └─base-devel
├─base
├─base-devel
├─pacman-contrib
│ ├─downgrade
│ └─rebuild-detector
├─pacutils
│ └─rebuild-detector
├─pahis
├─pkgfile
└─yay

Thanks for your reply. What’s the command to check which application requires these dependencies? In this case Electron 26 & 28. Thanks again.
What’s the correct command to make the orphans removal? Is it “sudo pacman -Rns XXX”? But how do I use pipe the result of “pacman -Qdt” as XXX? Thanks.
Don’t do that. You probably have yay or paru installed, so just run:
yay -Yc
or
paru -c

Awesome. It’s required by “drawio-desktop”. Thanks a lot! Is it possible if you can take a look at my other post?
