Moderation

Module which contains logic to handle moderation based features.

Flow for joining a room with the waiting-room enabled:

Joining the room

JoinSuccess

When joining a room, the join_success control event contains the module-specific fields described below.

Fields

Field	Type	Always	Description
raise_hands_enabled	bool	yes	If raise hands feature is enabled
waiting_room_enabled	bool	no	If waiting room is enabled
waiting_room_participants	Participant[]	no	A list of participants in the waiting room; see Participant

Example

For a moderator, the message would look like:

{
    "waiting_room_enabled": true,
    "waiting_room_participants": [
        {
            "id": "00000000-0000-0000-0000-000000000000",
            "control": {
                ...
            },
            ...
        },
        {
            "id": "00000000-0000-0000-0000-000000000001",
            "control": {
                ...
            },
            ...
        },
        ...
    ],
    "raise_hands_enabled": true
}

For a non-moderator participant, the message would look like:
