What CMS can be used to implement this functionality?

Question

CMS

The Contractor registers, enters all the necessary information, confirms consent to the processing of personal data, and awaits verification. Verification is performed from the admin panel of the system owner. The owner sees all the information about the person who wants to register: refuses or gives consent using the "Confirm" and "Reject" buttons.
As soon as the Contractor's account is confirmed, he receives a notification with the rules and instructions for working with the service and gets the opportunity to view responses to posts that are on the main page. Without a confirmed registration, this is not possible. When viewing what he likes, he presses the "To work" button, receives contacts by mail or SMS.
The customer registers (name, surname, phone number), after registration, he receives a unique key and rules in a letter, which he must provide to the Contractor if they agree with him. In order to confirm the start of work and a successful transaction, the Contractor presses the "Confirm transaction" button, where he enters the key provided to him by the Customer.
Is it possible to do this in the forum engine? And if so, which one is best suited for these purposes?
