Need help with IK Implementation (Inverse Kinematics)

Hello! I am working on a little project and I am facing some issues involving Inverse Kinematics.
I am making a robot that faces the player and I want to add a detail where there’s a hinge that holds the robot head up to the wall. However, I want to make that hinge IK Based.

How would I implement Inverse Kinematics? I’ve looked on YouTube, the DevForum, but I found nothing. I heard Roblox Studio has a feature called ‘IK Dragger’, that’s what I preferably want to use, but many articles explaining it I believe are outdated.

If you possibly know how to implement IK, please let me know!
