Whether the accessibility node is exposed to screen readers. The default value is true.
This property controls the visibility of the node to screen readers, ensuring that only relevant elements
are accessible to the user. For example, elements that are covered by a modal view should not be
accessible.
If this property is set to false, the screen reader ignores the node and prevents the user from focusing
on it. This is useful when temporarily disabling the node is preferred over removing it from the hierarchy.
