Use IconButton to render Icon-only buttons without the default button styles.
IconButton requires an aria-label, which will provide assistive technologies with an accessible label.
The aria-label should describe the action to be invoked rather than the icon itself. For instance,
if your IconButton renders a magnifying glass icon and invokes a search action, the aria-label should be
"Search" instead of "Magnifying glass".
