Use a group for area entered instead of a list of nodes

Question

func _on_[object group here]_area_entered(area: Area3D) -> void:

how do I use an object group instead of a node in a func declaration?

It’s only a function name, it doesn’t actually care about the node name, or what signal it’s connected to.
