I want sequence diagram please!!!!

We are interested in developing an application for managing roadside assistance for malfunctioned vehicles on roads. The system aims to automate the process and efficiently provide help. To be able to use the system, the customer should be registered in the system. Registration details include the customer's name and phone number. Moreover, the customer should register the vehicles he wants to have in the roadside assistance program. The customer can register as many cars as he wants. The customer should enter each registered vehicle's make, model, year, and plate number. At any point in time, the customer can request assistance using the system. Assistance types may include basic repair, tire change, gas refill, oil services, and towing to a service center. Each service has a price and may include buying some parts. Each part has its own price, and the service might require multiple parts of the same type. Multiple providers can offer the same service. The system should automatically select the closest provider to the requester. The customer can use the system to request assistance multiple times per year. Also, the request can include several services. However, each request should have a separate bill. The service provider is responsible for closing the assistance request after finishing his task. Once the service is closed, the cost to this service is calculated, and the customer is notified. Homework 5- bonus: Given the above problem description, you are required to come up with: 1) the sequence diagram for the "Request Assistance" use case
