the keyboard shortcut help message is not rendered by screen readers

[cyberbaloo]

Bug Report

Problematic behavior
When the video receives keyboard focus, a message appears visually: "Ctrl+Shift+/: access shortcuts directly." This message is contained in a div without an ARIA role or live region. It is not announced by screen readers.

Note: the given shortcut does not work on Mac. On Mac it is Control + Shift + /

Expected behavior/code
The keyboard shortcut help message must be announced by the screen reader when it becomes visible, i.e. when the video receives focus. This can be implemented via a role="status" or aria-live="polite" attribute on the message container.

Steps to Reproduce

1. Enable a screen reader
2. Navigate with the keyboard to the participant's video tile
3. Note that the message "Ctrl+Shift+/: access shortcuts directly." is not announced

Critère 7.1 : Chaque script est-il, si nécessaire, compatible avec les technologies d'assistance ?

Impact
A blind user navigating with the keyboard reaches the video without being informed of the Ctrl+Shift+/ shortcut that allows access to the application's keyboard shortcuts. They cannot discover this navigation feature without seeing the screen.

Hello @cyberbaloo I can't reproduce the issue,

my screen reader ( NVDA ) announce it correctly : "Ctrl+Shift+/ : accéder directement aux raccourcis."
when the help message shows up
