When any of the backend is used 'anonymous', 'jitsi-anonymous', 'internal_hashed', 'internal_plain', 'cyrus' and a participant becomes a moderator, because of external module or because set from jicofo we send to client with the self-presence about becoming moderator a default set of permissions which can be controlled via prosody config.
If using 'token' authentication the above applies only if there is a token and the token does not contain context.features.
If we are not requesting any transcription, `language` will be `null` so
take that into consideration when checking if we should stop processing
a transcription message after firing the API event.
Fixes: https://github.com/jitsi/docker-jitsi-meet/issues/1997
* fixtranscript results from whisper may have json.language="zh-TW" also requesting transcriptions language could be "zh-CN". Use _getPrimaryLanguageCode func to compare only the main lang code.
* fix: lint issue
If a non final transcript was displayed and then hidden and then we receive a final transcript we remove the part that has already been shown before. If the final transcript is the same as the non final that was already displayed we don't show the final.
* fix(subtitles): Handle errors to revert to default state.
* fix(transcribing): Handle transcriber status changed.
Drops potential transcribers and hidden participant actions and handling. Expect ljm to detect transcriptions on and off.
* feat(transcriptions): Adds a notification if transcriber leaves abruptly.
* squash: Renames action.
