Adding on to this ticket here, there are several buttons that are missing a descriptive text so that screen reader users can be presented with the function of the button.

1. In the Log In page, the show/Hide Password button
   
2. In the Agent List page:
   A. Dark Mode/Light Mode button
   B. Notification button
   C. Next/Previous page buttons
   
   Note: The buttons listed above have the descriptive text missing in the User List page as well.
