        let updatedActivity: Partial = {
            "id":  ActivityID, 
            "channelId": context.activity.channelId,
            "channelData": context.activity.channelData,
            "conversation": 
                            {
                              "name": "",
                              "id": context.activity.conversation.id,
                              "isGroup": context.activity.conversation.isGroup,
                              "conversationType": context.activity.conversation.conversationType,
                              "tenantId": context.activity.conversation.tenantId
                            },
            "type": "message",
            "text": "",
            "summary": "",
            "attachments": [ attachment ]
        }       await context.updateActivity(updatedActivity);
