title: Excel javascript custom functions deployement
body: <p>Now that I built <a href="https://docs.microsoft.com/en-us/office/dev/add-ins/tutorials/excel-tutorial-create-custom-functions?tabs=excel-windows" rel="nofollow noreferrer">my first Excel javascript custom function</a>
  I want to deploy it so users can add it in their sheets, but didn't find any useful infos. My questions:</p>
  <ul>
  <li>What to deploy exactly? (manifest, js files...)</li>
  <li>Where to deploy? Is a shared folder enought?</li>
  <li>Do I need NodeJs in client machines?</li>
  </ul>
