membersAddedEventMessageDetail resource type

Namespace: microsoft.graph

Represents the details of an event message about members added. This message is generated when members are added to a chat, a channel, or a team.

Note: The visibleHistoryStartDateTime property for a conversationMember and the membersAddedEventMessageDetail message might have different values if the selected shareHistoryTime value for members in a chat is earlier than the initiator’s visible history time.
