title: Pass data to a popover in Ionic 5
body: <p>In Ionic 3, passing data to a popover was as simple as:</p>
  <pre><code>let popover = this.popoverCtrl.create(PopoverPage, {key1:value1, key2: value2});
  </code></pre>
  <p>and it could be retrieved with <code>navParams</code></p>
  <p>How do you achieve the same in Ionic 5? The documentation says nothing about passing data.</p>
