The accessibility node behaves like a search field.
Platform-specific behavior
On Android, subscribe to the AccessibilityNode.invoked event to put the search field into edit
mode when the user activates it, so that it can receive hardware keyboard input.
On Windows and macOS, subscribe to the AccessibilityNode.focusChanged event to select the
search field represented by the node when the user navigates to it, so that it can receive keyboard input.
