Sorry that it took a while. I am preparing for high school exams.
Here is a screenshot with all the changed variables in the physics constraint. Don’t forget to turn on the physics simulation on the door piece and add collision with the proper setup of the channel to your VR controllers. It is important to set the tolerance to zero otherwise you can push from the top of the doors or use friction and push the doors down which is unnatural. If you want your doors to swing less or return to posïtion you can follow the tutorial.
I hope this is helpful enough.
