group property
Group is whether the transport carries multi-person rooms — a Discord guild channel, a Slack channel, a Teams channel or group chat, a Telegram group or supergroup. False on whatsapp alone, which has no such room to carry.
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
bool? group;
