Run shell script when Alacritty starts

Question

I'm on macOS Monterrey 12.6.1 with Homebrew installed Alacritty.

I want to run a script when Alacritty launches, echo Hello!

I have this in my alacritty.yml config. But it doesn't work:

shell:
  program: /bin/zsh
  args:
    - -c "/full/path/to/myScript/hello.sh"
