    Please analyze the following code file and determine whether it belongs to any of the provided modules based on the listed module descriptions.
    Note that the provided list of modules may not be exhaustive, and some files may not belong to any of the modules. 
    If the code belongs to a module, Only output the module name, without any explanation or additional information; otherwise, return 'None' if it does not belong to any module.

    Modules : {
        "UI": "Handles the front-end user interface, consisting of HTML, CSS, and JavaScript files generated by the Angular framework. It processes user requests and interacts with the server using AJAX for data retrieval and client-side interactions."
"Test Driver": "Facilitates automated regression testing and handles transmission of test data in JSON format. It performs Java testing using TestNG and JavaScript unit-testing with Jest. It also sets up a simulated web server for servlet-level tests and automates end-to-end testing using Selenium Java."
"Logic": "Manages the business logic of TEAMMATES, including handling relationships between entities, managing transactions, input value sanitization, access control rights, and interfacing with GAE-provided or third-party APIs."
"Storage": "Performs CRUD operations on data entities, validation of data, and abstraction of GQL queries, hiding the complexities of datastore from the Logic component."
"Common": "Contains utility classes, custom exceptions, and data transfer objects used across the entire application for easy consolidation and transfer of structured data."
"E2E": "Handles end-to-end testing and load & performance testing, providing helpers, abstractions of browser pages, and test cases for E2E tests and L&P tests."
"Client": "Contains scripts for administrative tasks, such as migrating data to a new schema and calculating statistics. This module connects directly to the application back-end for administrative purposes."

    Code: package teammates.ui.webapi; /** * Exception thrown when an entity is attempting to request for resources it does not have permission for. * * <p>This corresponds to HTTP 403 error. */ public class UnauthorizedAccessException extends Exception { /** * Indicates whether the error message will be shown to the user (as the API response). * If this flag is set to "false", a generic error message will be displayed instead. * The actual error message is always displayed to admin in the logs. * * <p>As this exception involves access control, the error message need to be redacted * in most cases because the full error message can give clues as to what needs to be done * in order to get the access (which should be unauthorized). * While it is true that there is little that user can do to elevate his/her privilege * even with that knowledge, we still need to do our part. * * <p>There are, however, some cases whereby the error message would be legitimately helpful * to users, e.g. when submitting responses to a feedback session that has not opened yet. * For such cases, it is appropriate to set this flag as "true". */ private final boolean showErrorMessage; public UnauthorizedAccessException(String message) { this(message, false); } public UnauthorizedAccessException(String message, boolean showErrorMessage) { super(message); this.showErrorMessage = showErrorMessage; } public boolean isShowErrorMessage() { return showErrorMessage; } }
