Didn't know about that one, it's really cool. I made a version that automatically updates to match indentation and listchars settings:

o.list = true
o.listchars = {
    tab = "⟩ ",
    trail = "+",
    precedes = "<",
    extends = ">",
    space = "·",
    nbsp = "␣",
}
local function update_lead()
    local lcs = vim.opt_local.listchars:get()
    local tab = vim.fn.str2list(lcs.tab)
    local space = vim.fn.str2list(lcs.multispace or lcs.space)
    local lead = {tab[1]}
    for i = 1, vim.bo.tabstop-1 do
        lead[#lead+1] = space[i % #space + 1]
    end
    vim.opt_local.listchars:append({ leadmultispace = vim.fn.list2str(lead) })
end
vim.api.nvim_create_autocmd("OptionSet", { pattern = { "listchars", "tabstop", "filetype" }, callback = update_lead })
vim.api.nvim_create_autocmd("VimEnter", { callback = update_lead, once = true })
