Extract Bone Location and Rotation using an Animation Modifier

Hello everyone, I’m looking for help with extracting the ‘World Location’ of a bone, as it is called in the animation’s Details pane, or more precisely, its position relative to the root, and converting it into a curve within the animation itself.

After some research, I created the following AnimModifier, but the values I get don’t match the ones displayed in the Details panel. Probably, I’m not understanding the meaning of BonePose.

The project is in Unreal Engine 4.26, and as a humble designer!
