In your case, it will be better if you contact the specialists involved in repairing the doors. It's just that if you don't want to break it anymore, then don't touch anything. I had a similar situation. I found various video tutorials that were supposed to help me, and I finally broke down my door. I had to order a new door, and I was lucky to come across the door design lab. A week later, I had a new door, but I learned a lesson that it is better to ask for help than to try to solve the problem myself.
