Oculus Interaction SDK problems and missing components

Hello, I've been attempting to port a small Unity game into Quest, and I've followed Valem's tutorials on Youtube (https://www.youtube.com/watch?v=XOc71-Og0Kg), which are very helpful. However, several times he uses many "Pointable" components, such as Pointable Plane and Pointable Cylinder, which simply dont appear in my editor. This is affecting my ability to properly create interactable UI/canvas and also pushable buttons. I'm using Unity version 2021.3.4f1. Any workarounds on this?

On another matter, my hands also do not appear while in Play mode. If I Build & Run on the quest, both hands and controllers work fine, but if I test the app while linked and on Play mode, only the controllers work and the hands dont show up. Any help here too?

PS: Also, along the way of trying workarounds, I've made an unknown oopsie and suddenly no interactions work anymore (and I dont have the previous version). Like, the scene, objects and hands/controllers load, but I cant interact with anything anymore : ( . Any ideas where the problem might be/where to check? I tought it was a Layer thing, but I checked and all Objects are on Default, and the references are where they should be.
