How to use the keypress.enableMouse function in keypress

process.stdin.on('mousepress', function (click) {
    if (click.release) {
      space_or_mouse();
    }
  });

  process.on('exit', function () {
    //disable mouse on exit, so that the state is back to normal for the terminal.
    keypress.disableMouse(charm);
  });

  process.stdin.resume();

  charm.reset();
  keypress.enableMouse(charm);
  botSay("Hey! Let's start solving!");
  botSay('The session starts now!');

  start_inspect = print_help(right_row_num, 1);

  charm.position(1, start_inspect)
  start_inspect += prepNewSolve();

  start_time = (new Date()).toTimeString().split(' ')[0]

  var total_time = new Stopwatch();
  total_time.start();
  charm.position(1, start_inspect);
};
