title: ExtJS Modern - Add multiple buttons to grid cell
body: <p>In ExtJS Modern 6.2 how can I add multiple buttons to a grid cell?</p>
  <p>I have seems examples using <code>widgetcell</code> but this seems to only work for a single button.</p>
  <p>What I would like to do is have 2 buttons where one is always hidden depending on value in row.</p>
