Foot Ik Messing Up Montage

I’ve experimented with the IK Rig node but it doesn’t seem to do anything but I am also unsure how to use it correctly. Its plugged in where the Control Rig node was and has the default IK_Mannequin rig set as the Rig Definition Asset.

Do you have any info on how it should be used? I cant seem to find much on using it in an anim bp, Just IK rig set up.
