How can I find the Group my item is part of in CoBlocks?

I’m using an Advanced Collision Event and want to trigger the deletion of the Group when the Camera collides with one of the Items in the group. The code looks like this:

This doesn’t work, because the parent/child relationship is not the same as the Group/Item relationship. I’ve tried a number of different ways to extract the Group from the Item, but without success.

If anyone has had success with this, I’d love to hear about it! (I haven’t looked into doing this with JS/TS yet)

Many thanks,
