UML Model

Hello I need help creating a UML Model (Unified Modeling Language) base on this User Story. Thank you in advance.

User Stories These are the minimum requirements for the system. Keep in mind that some of these re- quirements may imply other requirements 1. Sales As a barista, I can enter create a customer order. 1. The order form must include a menu that allows choosing the product 2. As menu items are selected, the total amount (including 10% tax) must be shown a. on the entry form b. As a barista, I can see my sales for the day. I am not allowed to see the sales figures for any other sales person or the shop as a whole 2. Manager As a manager, I can choose to review the total sales for any date range 1. The start date must be before the end date As a manager, I can review the sales figures for a particular barista As a manager, I can maintain inventory for the shop 1. a. b. c. The inventory must be modified every time there is a sale As a manager, I can manage employees (add, remove) and change their pay scale 1. d. Records for an employee who is removed must be maintained, and there must not be any errors do to the removal Part of your task, as mentioned in the requirements below, is to develop test cases to go along with the user stories. For example, a test case for creating a customer order might be "An order cannot be created for an item whose inventory count is 0
