You can configure Neovim to either auto reload or to ask you whenever a file is changed. (Can't remember which one is the default, probably to ask.)

I'm ~80% sure auto-reload is on by default, and 100% sure that it's on in a fresh LazyVim install.

vim.o.autoread (default on) When a file has been detected to have been changed outside of Vim and it has not been changed inside of Vim, automatically read it again.

Thanks, just found something about that.
