How to Launch GUI Applications on Mac OS?

How may I configure Nix 2.15.1 to launch applications on Mac OS Ventura 13.4 without first launching a terminal? For example, currently, when I double-click ~/.nix-profile/bin/alacritty via the Finder file explorer an iTerm2 instance is launched which then executes the alacritty binary.

Did you look in ~/Applications ?
