title: MUI DataGrid - Open GridColumnsPanel
body: <p>In the MUI DataGrid, by clicking the options menu on any header column, you can access the column visibility panel.</p>
  <p>But I haven't found a way to display this panel from outside the Grid. The idea was to have a button that, when clicked, could display the panel. Even if it remains with its position inside the Grid</p>
  <p>This would avoid having to build a component for this purpose.</p>
