[add an example for instancedmesh selection by chiguaboy · Pull Request #22976 · mrdoob/three.js · GitHub](https://github.com/mrdoob/three.js/pull/22976/commits/7911d1d8e6211baaf27dfe3348fb6553e719d929) Today, I can’t see this example but in SelectionBox I can still confirm the SelectionBox.instances property. I want to confirm whether the property can be used in future or do we perfer this usage ?

It was never merged. Someone tried to add it but they said it wasn’t needed. It’s in the discussion of the pr you shared
