How to move hips in Unity Animation Rigging IK

I'm currently working on a game almost similar to this: https://www.instagram.com/p/COQWr5jH-79/?igshid=r7pbr62re6he

I am already able to make the limbs and head follow just like in the video using Two Bone IK Constraint. However, I'm having trouble recreating the hip behaviour.

Any tips on how to do this? Any constraint combination I should use?

Any help is appreciated, thank you!
