Which is the easiest way to install KDE Connect in my Steam Deck?

I know I can install it using Pacman but for that I need to create a root password and then run some command to install programs on the OS which is immutable, but honestly if all I want is to install KDE Connect I see unnecessary to do all that, isn't there a simpler way?

I already tried with flatpak but there is no KDE-Connect repository in flatpak, and following this Reddit tutorial doesn't really lead to anything since the repository seems to be dead.

Edit: KDE Connect came pre-installed in the Deck.
