Can you assist me with an activity diagram for the below.

Students want to use an intuitive system and HR needs to ensure standard practices are followed.

The LMS meets global accessibility standards.

The LMS provides a user-friendly and accessible UI for all users.

Users access the LMS and are initially presented with a well-organised UI that displays each module that a specific user has permission to. This conforms to the device type with simple navigation and a responsive design.

A user access their first module (e.g. course content) and needs to use an accessibility feature.

A user clicks the easy-to-find icon that displays the options (eg keyboard navigation, alternative text for images, scalable fonts, etc).

The user selected "Alt Text" and the change is reflected on the entire LMS (on a per-user basis).
