Using gizmo manager on the root node of glb/gltf

Hi everyone! Quick question that I’m struggling with:

How to use gizmo manager with a gltf or in any case a transform node that has children. I want to move the whole packet together :smiley:
Here is the smallest playground that illustrates what I would like to do but no controls appear when I try to click the mesh:

It seems that using additionalTransformNode works but it is a bit confusingly named?

Edit: It should be used with bones it seems, is this a correct way to go?… I might also need more meshes to be gizmozed so :scream:

What the heck is this; if I clone the mesh it does work with the manager :smiley:

Ugh now the attachable nodes seems to work!
