Can't populate Menu component with jumplist

[vunhatchuong]

I want to populate lines with the content of Vim's jumplist. but vim.fn.getjumplist()[1] returns empty table.

local Menu = require("nui.menu")

local function get_jumplist()
    local jumplist = vim.fn.getjumplist()[1]
    local formatted_jumps = {}

    for i, jump in ipairs(jumplist) do
        local bufname = vim.fn.bufname(jump.bufnr)
        local line = jump.lnum
        local col = jump.col
        local text = string.format("%d: %s | Line %d, Col %d", i, bufname, line, col)
        table.insert(formatted_jumps, Menu.item(text, { jump = jump }))
    end

    return formatted_jumps
end

local menu = Menu({
    relative = "win",
    anchor = "NE",
    position = {
        row = 0,
        col = vim.api.nvim_win_get_width(0),
    },
    size = {
        width = 50,
        height = 10,
    },
    border = {
        style = "single",
        text = {
            top = "[Jumplist]",
            top_align = "center",
        },
    },
    win_options = {
        winhighlight = "Normal:Normal,FloatBorder:Normal",
    },
}, {
    lines = get_jumplist(),
    max_width = 50,
    keymap = {
        focus_next = { "j", "<Down>", "<Tab>" },
        focus_prev = { "k", "<Up>", "<S-Tab>" },
        close = { "<Esc>", "<C-c>", "q" },
        submit = { "<CR>", "<Space>" },
    },
    on_close = function()
        print("Menu Closed!")
    end,
})

Overall, I struggle to do things when inside the Menu({}). So this also doesn't work:

        on_change = function(item, _)
            local came_from = vim.fn.winbufnr(vim.fn.win_getid(vim.fn.winnr("#")))
            local jump = item.jump
            if jump then
                vim.api.nvim_win_set_cursor(came_from, { jump.lnum, jump.col })
            end
        end,

I want to have the functionality that when you hover over an item it will jump to the line to preview it.
