Answer this ASAP. Don't use CHATGPT. Last time, you gave me the exact same answer from which is incomplete and inappropriate. Make sure you answer both A and B completely $($by drawing UML use case diagram $)$

A private neighborhood clinic wants to automate management of their operations by implementing an interactive web$-$based software system using the latest html$5$ standard which should make the system run on tablets and smart phones as well as desktop and laptop machines. The Clinic Management System $($CMS$)$ is to be used by both patients and clinic personnel $($doctors$,$ nurses, and administrative staff$).$ A patient will be able to make on$-$line appointments for an examination, cancel an existing appointment, inspect lab results, check their outstanding balance and make payments using their credit cards. A doctor will be able to record their schedules for time periods they are busy and periods they have time$-$off. They will also be able to browse their specified period, in case they become unavailable for unexpected reasons, ask to cancel appointments during a past period. Initially only some brief responsibilities. A doctor may subject to approval by clinic director, $($including picture and patient records in chronological order$).$ A nurse patient but the doctor may ask for details subject to approval by the head nurse $($head nurse displayed for each patient but the doctor patients, including administrative staff can only read but not modify. A nurse will be able to request time$-$off using CMS$,$ where such a user does not help patients, doctors and herself$/$himself reports to the clinic director. The module and clinic personnel $($their access to the Internet. The access to perform operations on their behalf, in situations due$)$ and put in place by the clinic when they first started operation of the clinic for both customers $($for instance, such a system with sensitive information for both patients and clinic personnel in addition to existing software only about a couple of hundred active patients but as time goes by$,$ especially after it is in place, the clinic management expects to have at least thousand. User authentication is especially critical for customers, the clinic management has also decided to put in place personal. In addition, clinic currently has with varying privileges. One can become a silver, gold or platinum type of patients if not more. To attract new customers, the clinic management have also decided to put two types of service and gold$)$ of memberships in place at least two years. A customer who has been a silver customer for at least two years gets pretty regularly for assuming they have never failed to make payments on their dues. Both silver and gold customers are provided with more flexible time slots for making appointments and gold customers also get a bonus system, getting an SMS notification when their lab results are ready. Gold customers get additional privileges such as getting an SMS notification when their lab results are ready.

A$)$ List and justify two non functional requirements for this system.

B$)$Identify actors and use case for the system described above and show them on a UML use case diagram.
