Initiating a group chat

Trinetra-MSFT the documentation at https://docs.microsoft.com/en-us/azure/bot-service/rest-api/bot-framework-rest-connector-api-reference?view=azure-bot-service-4.0#conversationparameters-object did not specify which parameter is required.  Per the example where creating a 1:1 conversation with the REST API, the parameters were 

{
	"type": "message",
	"isGroup": false,
	"members": [
		{
			"id": "Some Id"
		}
	],
	"tenantId": "Some Id",
	"topicName": "test"
}

I only updated the parameters by changing "isGroup" to true and added another member's id in the "members" array.

No bot Ids were were added to the "members" array
