Timeout mechanism is not screen reader accessible

Rule
If there is a session time limit, users MUST be warned before the session ends and MUST be given time to save their data and/or extend the session.
Background
People with disabilities such as blindness, low vision, mobility impairments, and cognitive limitations may require more time to read content or to perform functions such as filling out online forms. If a session has a time limit, it may be difficult or impossible for some users to perform the required action before a time limit occurs. People must have the ability to turn off or extend time limits while interacting with content. Giving people the ability to turn off or extend the time helps ensure that they can complete tasks.
How to Fix
When a timeout warning and mechanism to extend a session are not compatible with screen readers, the requirement is not met.
Fix this issue by ensuring that both the timeout warning message and the mechanism to extend the session (e.g. the button) are keyboard and screen reader accessible.
