How to reproduce the issue?

1. Open URL: https://compulim.github.io/webchat-loader/ and sign in using valid credentials.
2. Navigate to web chat page and select 4.18.1-main.20240927.ea7a875 (30/9/2024) version and then select mockBot link under present label and then select open web chat in new window link at bottom.

   4.Video vimeo will appear.

What do you expect?

The “Translate audio” control is fully keyboard accessible, meaning it can be reached using the Tab key, clearly receives visible focus, and can be activated using standard keyboard keys (Enter/Space). All associated options (e.g., language selection) are also operable via keyboard and properly exposed to assistive technologies.

What actually happened?

"Translate Audio" control which is present under video is not keyboard accessible. Here we used tab, Shift+Tab, UP/Down arrow key.
