roomId property
RoomID is the conversation on the ORIGINATING transport, and the value to send back as room.id: a Discord channel snowflake, a Slack conversation id (D… IM, C… public channel, G… private or mpim), a Teams conversation id (19:…@thread.… for a channel or group chat, a:… for a personal chat), or a Telegram chat id in decimal (negative for a group, positive for a DM). It is stable for the life of the room, so every message from one conversation carries the same value.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? roomId;
