How to make <cr> behave like gf in a given situation?

[voyeg3r]

Let's say my cursor is over ~/.config/init.lua or "core.keymaps". I already have tried:

vim.keymap.set("n", "<cr>", function()
  local path = vim.fn.expand("<cfile>")
  local ok, result = pcall(vim.cmd, 'gf ' .. path)
  if not ok then
    return "<cr>"
  end
  -- If 'gf' succeeded, return an empty string to prevent further actions
  return "gf"
end, { expr = true })

But for not avail
