Referencing a child node of a group?

NJL64

Is there a way I can access the child node after this?: @onready var bumper = get_tree().get_nodes_in_group("bumper_group")

I tried: @onready var anim_bumper = bumper.get_child(1)
but I don't think that works.

I want to play the animation node. (The script is not attached to the node that is in the group)

EDIT:
I also tried

@onready var bumper = get_tree().get_nodes_in_group("bumper_group")
@onready var anim_bumper = bumper.get_node("AnimationBumper")

But it said invalid call

get_nodes_in_group() returns an Array[Node], not a Node.
https://docs.godotengine.org/en/4.5/classes/class_scenetree.html#class-scenetree-method-get-nodes-in-group

Each element of the Array is a Node, with these methods:
https://docs.godotengine.org/en/4.5/classes/class_node.html#methods

So this would reference the first child node (child index 0) of the third node (array index 2) in the Array:
bumper[2].get_child(0)

DaveTheCoder Thank you! It was so simple, yet so hard to find a straight answer. Thank you as well for letting me know that its an array, and about all the methods.
