Controller driven hands don't trigger custom grab poses in Interaction SDK

Hello, in the Interaction SDK sample if I use controller driven hands and try to grab the mug I can pick up the mug by pressing the controller side button, but it just "sticks" to my hand and the custom grab poses are never triggered. Pure hand tracking does trigger the custom poses.

Are custom grab poses supported for controller driven hands? I'm currently using the "Hands Only" procedural controller hand behavior on my VR pawn blueprint. I would like to grab objects while holding a controller, but still use the custom poses so the virtual hand wraps around the objects more naturally. I'm using a Quest 3 headset and Unreal 5.5 with the Meta interaction SDK plugin v77.
