The ML4W Dotfiles include a configuration for a dock based on nwg-dock-hyprland.

You can activate it by installing the package with:

yay -S nwg-dock-hyprland

Then add the following command to the file ~/.config/hypr/conf/custom.conf

exec-once = ~/.config/nwg-dock-hyprland/launch.sh

And login to Hyprland again.
