title: UICollectionViewCompositionalLayout setting section.orthogonalScrollingBehavior page programmatically?
body: <p>I am implementing a <code>UICollectionViewCompositionalLayout</code> and using </p>
  
  <pre><code>section.orthogonalScrollingBehavior = .groupPagingCentered
  </code></pre>
  
  <p>to scroll a section horizontally.</p>
  
  <p>This lets a user scroll from page to page in a section horizontally.</p>
  
  <p>I use </p>
  
  <pre><code>section.visibleItemsInvalidationHandler = {...}
  </code></pre>
  
  <p>to get the page a user scrolls to.</p>
  
  <p>How can I scroll to a page in this section programmatically?</p>
