Announcements from the moderator to a single participant

Scenario description

There is sometimes a need to communicate certain information during the conference to one of the participants verbally, such as asking them to prepare for a presentation or to resolve any technical issues on their end.

To do this, the moderator connects to the conference in a way that they do not appear on the layout, for example, by disabling the camera in the settings of their connection in the conference management interface, and assigns themselves an outgoing audio channel that is not used by other conference participants.

Then they add the corresponding incoming audio channel to the participant (the recipient of the voice message) and make an announcement or notify them of the issue.
