Use HiddenTextExpander to indicate and toggle hidden text.
Accessibility
HiddenTextExpander requires an aria-label, which will provide assistive technologies with an accessible label.
The aria-label should describe the action to be invoked by the HiddenTextExpander. For instance,
if your HiddenTextExpander expands a list of 5 comments, the aria-label should be
"Expand 5 more comments" instead of "More".
