How to make sure ts_utils will be loaded in this function?

Lua
1 
M.toggle_boolean_value_on_line = function()
  local ts_utils = require("nvim-tressitter-ts.utils")
  local line = vim.api.nvim_get_current_line()
  local booleans = ts_utils.get_all_tokens_of_type(line, "boolean")
  local cursor_pos = vim.api.nvim_win_get_cursor(0)[1]

  if #booleans == 1 then
    booleans[1].value = not booleans[1].value
  else
    for i, boolean in ipairs(booleans) do
      if cursor_pos == boolean.range.start then
        boolean.value = not boolean.value
        break
      end
    end
  end
end

Use pcall

local ok, ts_utils = pcall(require, "nvim-treesitter-ts.utils")
if not ok then
  return
end
