How to auto open files when browsing explorer?

[gestate-8]

I'd like files to open automatically in the right buffer when I move to them using jk in the Explorer.
Is there a good way to achieve this? Thank you.

Actions

Open new buffer on list_down/list_up:

opts = {
  picker = {
    sources = {
      explorer = {
        win = {
          list = {
            keys = {
              ['j'] = { { 'list_down', 'jump', 'focus_list' } },
              ['k'] = { { 'list_up', 'jump', 'focus_list' } },

Replace the main window's buffer on list_down/list_up:

opts = {
  picker = {
    sources = {
      explorer = {
        actions = {
          replace_main = function(picker, item)
            if not item.dir and picker.main then
              local buf = vim.api.nvim_win_get_buf(picker.main)
              vim.bo[buf].buflisted = false
              picker:action 'jump'
            end
          end,
        },
        win = {
          list = {
            keys = {
              ['j'] = { { 'list_down', 'replace_main', 'focus_list' } },
              ['k'] = { { 'list_up', 'replace_main', 'focus_list' } },

Preview main

Or you can simply set preview = "main":

Thank you very much!

I have checked the edited version as well.
It does open the buffer, which makes it a much more appropriate and accurate response to my original question.
Thank you very much for your help!
