Now What ?!?! please help

Now, use the test() method to test the string in text against the regular expression you just created. Remember the test() method returns a true or false value. Return the result... help me !!!

app.js 
// Type inside this function
function isValidHex(text) { const hexRegEx = /^#[a-f0-9]{6}$/i; }

const hex = document.getElementById("hex");
const body = document.getElementsByTagName("body")[0];

hex.addEventListener("input", e => {
  const text = e.target.value;
  const valid = isValidHex(text);
  if (valid) {
    body.style.backgroundColor = "rgb(176, 208, 168)";
  } else {
    body.style.backgroundColor = "rgb(189, 86, 86)";
  }
});
