Non-Fault Credit Service Query: Clarification on Responsibility and Repair Process

According to the relevant claim, I used the 'non-fault credit service' for the first time and was not clear about the details. On the morning after the accident, I filled out the claim information on your company's website and immediately received a call from Auxillis to arrange for the car repair. However, we were concerned that if we allowed Auxillis to repair the car first and ultimately your company judged the responsibility to be ours, we would have to pay for the repair costs.

Therefore, I would like to confirm the following points:

1. Has the insurance company finally decided that this accident is not our responsibility?
2. Will Auxillis only be responsible for repairing our car or will they also be responsible for determining the responsibility of the accident?
3. If we use Auxillis' service to repair our car first and later fail due to any reason, including the other party's appeal, will we need to pay the related costs?
4. What is the normal procedure for processing through Auxillis?
