How do I make the explorer opened when I open a file?

[griiid]

For example, when I execute nvim app.py, it only have a buffer which opened app.py.
I want the explorer is also opened, and focused on app.py.

I'm using LazyVim, I'll appreciate if you can tell me how to do this in LazyVim.
It's okay to tell me how to configure it without LazyVim.

vim.api.nvim_create_autocmd("VimEnter", {
  group = vim.api.nvim_create_augroup("open_explorer", {}),
  callback = function()
    -- Open scoped to the file's root directory
    -- Snacks.explorer({ cwd = LazyVim.root(), enter = false })

    -- Open scoped to the pwd
    local picker = Snacks.explorer.reveal({ buf = 0 })
    picker.opts.hidden = true
    picker.opts.enter = false
  end,
})

This won't focus the buffer. Should be Snacks.explorer({ cwd = LazyVim.root(), enter = false }). Or change opts.hidden = true to opts.enter = false. Also no need to define buf = 0, since this will be default.

Personally I'd go with the commented line to also keep consistent behavior with default LazyVim.
