plugin dont work for me. with error: "Failed to run `config` for toggleterm-manager.nvim"

[dredstone1]

When I found your plugin(I found it in Reddit) I got excited, but when I add it to my configs it sometimes writes this error message(when i start neovim):

when i write ":lua require("toggleterm-manager").open({})" it throw this error:

when I write "Telescope toggleterm_manager" it throws this error:

This is my current toggleterm-manager.lua file:

return {
    "ryanmsnyder/toggleterm-manager.nvim",
    dependencies = {
        "akinsho/nvim-toggleterm.lua",
        "nvim-telescope/telescope.nvim",
        "nvim-lua/plenary.nvim", -- only needed because it's a dependency of telescope
    },
    config = true,
}

this is my toggleterm.lua file:

return {
    'akinsho/toggleterm.nvim',
    version = "*",

    config = function()
        require('toggleterm').setup {
            size = function(term)
                if term.direction == "horizontal" then
                    return 15
                elseif term.direction == "vertical" then
                    return vim.o.columns * 0.4
                end
            end,
            open_mapping = [[<c-\>]],

            hide_numbers = true,   -- hide the number column in toggleterm buffers
            autochdir = false,     -- when neovim changes its current directory the terminal will change its own when next it's opened
            start_in_insert = true,
            persist_mode = true,   -- when the term is closed it will not lose its state
            shell = vim.o.shell,   -- change the default shell
            close_on_exit = false, -- close the terminal window when the process exits

            auto_scroll = true,    -- auto scroll when new output is generated

            shade_terminals = true,

            persist_size = true,
            direction = 'horizontal',
            float_opts = {
                border = 'single',
                width = 150,
                height = 40,
                winblend = 3,
            },

            winbar = {
                enabled = false,
                name_formatter = function(term) --  term: Terminal
                    return term.name
                end
            }
        }
  end
}

I'm using windows.
the toggleterm is working.

I want to add that I just started neovim 2 weeks ago, so I still learning a lot of things
