How could I center the navbar accurately in CSS?

Question

It's being centered, but it views the left part of the text, not the center.

Thanks in advance.

Here's the important part of my HTML Code:

  nav ul {
  display: flex;
  justify-content: center;
  align-items: center;
}

nav ul li {
  display: inline-block;
}

nav ul li a {
  text-decoration: none;
  color: #fff;
  font-family: Helvetica;
  color: white;
}

body {
  background-color: tomato;
  ]

<nav>
  <ul>
    <li><a href="https://google.com">Menu</a></li>
    <li><a href="https://google.com">Menu</a></li>
    <li><a href="https://google.com">Menu</a></li>
    <li><a href="https://google.com">Menu</a></li>
    <li><a href="https://google.com">Menu</a></li>
  </ul>
</nav>
