Is IK Rig supported by Anim blueprint "templates"?

I have an IK Rig that functions well in my animation blueprint. For my project’s scalability however, I would like to implement a similar system inside an animation blueprint “template”, but here I seem unable to get any response when editing the values?

here’s an example on how I’ve implemented it.

Can someone confirm if IK Rig nodes are even supported in animation blueprint templates?

Cheers

After a lot of trial and error I figured out the root of what was bothering me:
IK Rig nodes work with Anim BP templates, but the child anim bp will permanently use the IK Rig parameter values set on moment of creation unless promoted to variables. Considering all values was set to “0,0,0”, it makes sense I didn’t see any effect.

Promoting all the exposed parameters to variables fixed it though.
