Previewing Output Pose for Troubleshooting

Hello,

I am not sure how to troubleshoot an output pose, not even sure what I should be searching for in terms of a tutorial. Specifically, I am trying to use the Two Bone IK node to move limbs (currently, just the left arm) to be level with a sloped floor during a fall animation. In the Two Bone IK documentation (Animation Blueprint Two Bone IK in Unreal Engine | Unreal Engine 5.6 Documentation | Epic Developer Community) it shows a troubleshooting example, but I am not sure how to go about recreating this. Here is a video of my unfixed fall and then an image of the corresponding code, which is using a trace from an AnimNotifyState in the animation sequence:


Additionally, nothing happens when I use the IK for the left hand, and I do have that baked properly (I think) in the animation sequence. Hand_l is in the same location. Here is a screenshot of that:


If I can troubleshoot this like in the documentation, then I can figure out what my effector location should be.

Again, just looking for general troubleshooting guidance, not a solution to this problem, in case I have not presented all of the necessary information.

Edit: I also have no preview of the fall animation in the preview window:


This is an animation layer in a child class of the main ABP following the Outcast Devschool Advanced Locomotion tutorial series on YT.

Last video and details of anim layer- trying bone space for the effector location and two AnimNotifyState tracks:


Again, how should I go about troubleshooting this? Please and thank you.

After sleeping on it, I realized I can just make a new ABP with the animation sequence looping + nodes + a new AnimNotifyState casting to the new ABP. I now have a preview. I am still not able to play the AnimSequence AND view the trace action during runtime (after placing the new animation sequence in the level), which would be nice to see on sloped surfaces, but I am sure I will figure out a way to place actors in the preview, or maybe change the default rotation of the preview animation on the floor provided in the preview window or something.
