You can install it via https://extensions.gnome.org. Alternatively, you can download the quick-app-launcher@leleat-on-github folder and move it to your extensions folder. Local extensions are in ~/.local/share/gnome-shell/extensions/. After moving the folder to the correct location, restart the GNOME shell (Alt+F2: enter r. On Wayland you need to logout).
