Which directory does the neovim load vim-plug script on MacOS?

Question

I am switching from vim to neovim. According to https://github.com/junegunn/vim-plug.

For Unix/Linux

sh -c 'curl -fLo "${XDG_DATA_HOME:-$HOME/.local/share}"/nvim/site/autoload/plug.vim --create-dirs \
       https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'

${XDG_DATA_HOME:-$HOME/.local/share}"/nvim/site/autoload/ resolves to ~/.local/share/nvim/site/autoload/. However when neovim start it does not load the vim-plug script from here.

I have tried to manually setting call plug#begin(~/.local/share/nvim/site/autoload/Plugged) however, neovim does not seems to load from this folder.

I have also referred to this post on stackoverflow, however no luck.
