vim-startify configuration in lua with custom functions - vim

Question

I'm trying to migrate my vimrc configuration to lua, and I'm stuck on migrating my vim-startify configuration. In particular, how can I write the gitModified and gitUntraked lists?
vimscript:
function! s:gitModified()
let files = systemlist('git ls-files -m 2>/dev/null')
return map(files, "{'line': v:val, 'path': v:val}")
endfunction
function! s:gitUntracked()
let files = systemlist('git ls-files -o --exclude-standard 2>/dev/null')
return map(files, "{'line': v:val, 'path': v:val}")
endfunction
let g:startify_lists = [
\ { 'type': 'dir', 'header': [' MRU '. getcwd()] },
\ { 'type': 'sessions', 'header': [' Sessions'] },
\ { 'type': 'bookmarks', 'header': [' Bookmarks'] },
\ { 'type': function('s:gitModified'), 'header': [' git modified']},
\ { 'type': function('s:gitUntracked'), 'header': [' git untracked']},
\ { 'type': 'commands', 'header': [' Commands'] },
\ ]
My current lua:
vim.g.startify_lists = {
{ type = "commands", header = { " Commands" } }, -- Commands from above
{ type = "dir", header = { " MRU " .. vim.fn.getcwd() } }, -- MRU files from CWD
{ type = "sessions", header = {" Sessions"} },
{ type = "bookmarks", header = {" Bookmarks"} },
}
Here I'm missing the two git related items.
Any idea?
Thanks in advance.

Here's what I did:
function CommandToStartifyTable(command)
return function()
local cmd_output = vim.fn.systemlist(command .. " 2>/dev/null")
local files =
vim.tbl_map(
function(v)
return {line = v, path = v}
end,
cmd_output
)
return files
end
end
vim.g.startify_lists = {
{type = "dir", header = {" MRU " .. vim.fn.fnamemodify(vim.fn.getcwd(), ":t")}},
{type = CommandToStartifyTable("git ls-files -m"), header = {" Git modified"}},
{type = CommandToStartifyTable("git ls-files -o --exclude-standard"), header = {" Git untracked"}}
}
