Neovim packer fzf config - apple silicon

[x] I have fzf 0.30.0 or above
[x] I have read through https://github.com/junegunn/fzf.vim/blob/master/README.md
[x] I have read through https://github.com/junegunn/fzf/blob/master/README-VIM.md
[x] I have read through the manual page of fzf (man fzf)
[x] I have searched through the existing issues

Works with minimal version

vim -Nu <(curl https://gist.githubusercontent.com/junegunn/6936bf79fedd3a079aeb1dd2f3c81ef5/raw)

issue: :Rg does not work as fzf.vim doesn't find Rg

Issue comes from mac silicon installing fzf and rg under the following dirs when using brew install

return require("packer").startup(function(use)
    -- Packer can manage itself
    use("wbthomason/packer.nvim")

    use("junegunn/fzf.vim")

end)

^ works for just :FZF

How can I specify the Rg dir?

junegunn / fzf.vim
