Take a look at hyprland’s gitlab repo for that. Those config files on the tutorial are old and a lot of stuff has changed.
hyprland config: etc/skel/.config/hypr/hyprland.conf · main · Garuda Linux 🦅 / Themes and Settings / Settings / Garuda Hyprland Settings · GitLab
The two files above it in tutorial: usr/local/bin · main · Garuda Linux 🦅 / Themes and Settings / Settings / Garuda Hyprland Settings · GitLab
I believe you can place the files in the /etc/skel and other dirs from gitlab repo in their right places.
