body: <p>I am trying to use NavLink in react typescript project, however, it's getting an error.
  Property 'activeStyle' does not exist on type 'IntrinsicAttributes &amp; NavLinkProps &amp; RefAttributes'.</p>
  <pre><code>import React from 'react'
  import { NavLink } from 'react-router-dom'
  
  export default function Nav () {
    return (
          &lt;nav className='row space-between'&gt;
            &lt;ul className='row nav'&gt;
              &lt;li&gt;
                &lt;NavLink
                  to='/'
                  activeStyle={{
