An Icon is a piece of visual element, but we must ensure its accessibility while using it. It can have 2 purposes:

• decorative only: for example, it illustrates a label next to it. We must ensure that it is ignored by screen readers, by setting aria-hidden attribute (ex: <Icon icon="check" aria-hidden />)
• non-decorative: it means that it delivers information. For example, an icon as only child in a button. The meaning can be obvious visually, but it must have a proper text alternative via aria-label for screen readers. (ex: <Icon icon="print" aria-label="Print this document" />)
