 This interactivity event node is activated when a “select” event occurs on a glTF node `nodeIndex` or on any node in its subtree subject to the following propagation rule: the lowest node in the tree receives the select event first, and the event bubbles up the tree until a glTF node with an associated `event/onSelect` behavior graph node with its `stopPropagation` configuration value set to `true` is found.
