Permissions applied in the Generic UI is not reflected in the React Client

We have an application with Cuba version 6.9.12. (We migrated the application to Cuba version 7.2.15 and generated a React Client out of it.) The React Client is invoking services from application with Cuba version 6.9.12.

Legacy Roles and Permissions - CUBA Platform. Developer’s Manual this doc states that “Also, in the previous versions, there were no security scopes, so all roles affected both Generic UI and REST API clients”.

However, the permissions such as the changes to the Entities permissions in the existing roles are not reflecting on the React UI. Regardless of the entity is allowed or denied on specific operations, the permissions are always true and UI is rendered/enabled. Am I missing something? Thanks in advance.
