How to use neovim configuration systemwide

I am trying to make sure that my neovim configuration gets used for all users. Basically I want my neovim configuration at ~/.config/nvim to be used on using the nvim command with sudo. Hence I copied ~/.config/nvim to /etc/xdg/nvim. The problem is that I am using astronvim and it uses an init.lua file and not init.vim. According to this I need a sysinit.vim file. Hence I created a sysinit.vim file but I am not sure about how I can import my Lua config file within sysinit.vim. How can make this happen?
