Remove "The session has ended" popup

[a.og...@entouch.co.jp]

Hi All,

Where in configuration can I turn off this window (see attached)?
I already set a logout URL when creating the session with the API, so I should not see this message.

BBB. latest version (June 15th 2022).
For reference, previous BBB versions from 2021, never showed this window.

Thanks, Ally.
