ChatBar.visible = true;

I used something like this to detect if it's open

//#CLIENTSIDE
function onKeyPressed(code) {
  if (keydown(8) || temp.code == 9) setTimer(0.05);
}

function onTimeout() {
  if (ChatBar.visible) {
    temp.text = ChatBar.text; //or ChatBar.getText()
    if (temp.text != null) {
      [Do your animation]
    }
    setTimer(0.1);
  }
}
