javascript – Why doesn't setTimeout see the function?

Question:

I'm trying to make a message on the success of any operation. As a result, I managed to make the message fly out in a second, but I can’t make the message be deleted after that, it says in the console that the function that closes the window was not found, what’s the problem?

btn = document.querySelector('button');
btn.addEventListener('click', function () {
  setTimeout('openWindow()', 1000);
})

function openWindow() {
	document.querySelector('.window').style.display = 'block';
  setTimeout('closeWindow()', 2000);
  function closeWindow() {
    document.querySelector('.window').style.display = 'none';
  }
}  
.wrapper {
  width: 600px;
  height: 400px;
  background-color: #21a1d7;
  position: relative;
}

.wrapper .window {
  width: 30%;
  position: absolute;
  height: 30px;
  background-color: green;
  right: 10px;
  top: 10px;
  text-align: center;
  color: white;
  display: none;
}
<div class="wrapper">
  <button>Открыть окно</button>
  <div class="window">
    Успешно!
  </div>
</div>

Answer:

btn = document.querySelector('button');
btn.addEventListener('click', openWindow)

function openWindow() {
   setTimeout(function() {
    document.querySelector('.window').style.display = 'block';

  }, 1111)
  setTimeout(function() {
    document.querySelector('.window').style.display = 'none';

  }, 2222)
}
.wrapper {
  width: 600px;
  height: 400px;
  background-color: #21a1d7;
  position: relative;
}

.wrapper .window {
  width: 30%;
  position: absolute;
  height: 30px;
  background-color: green;
  right: 10px;
  top: 10px;
  text-align: center;
  color: white;
  display: none;
}
<div class="wrapper">
  <button>Открыть окно</button>
  <div class="window">
    Успешно!
  </div>
</div>

Option two, as the author wanted to implement …
With bug fixes in the comments…

btn = document.querySelector('button');
btn.addEventListener('click', function() {
  /* не "openWindow()" и даже не openWindow() */
  setTimeout(openWindow, 1000);
})

function openWindow() {
  document.querySelector('.window').style.display = 'block';
  /* не "openWindow()" и даже не openWindow() */
  setTimeout(closeWindow, 2000);

  function closeWindow() {
    document.querySelector('.window').style.display = 'none';
  }
}
.wrapper {
  width: 600px;
  height: 400px;
  background-color: #21a1d7;
  position: relative;
}

.wrapper .window {
  width: 30%;
  position: absolute;
  height: 30px;
  background-color: green;
  right: 10px;
  top: 10px;
  text-align: center;
  color: white;
  display: none;
}
<div class="wrapper">
  <button>Открыть окно</button>
  <div class="window">
    Успешно!
  </div>
</div>
