Await async functions on commandPassThrough

[caioedut]

I just need to block user input while the async function has not ended.

this might help:

  const hideInput = () => {
    terminalRef.current.state.instances[0].instance.inputWrapper.style.display =
      "none";
  };

  const showInput = () => {
    terminalRef.current.state.instances[0].instance.inputWrapper.style.display =
      "block";
  };
