In Microsoft Teams, <Conversation>.ReplyToActivity does not send a reply, it creates a new message to the conversation about botframework-sdk

I think it's probably the same code, albeit a different usage scenario. In the other example, there was (I think) a 1-2-1 conversation between a user and a bot, where the OP wanted to perform a threaded reply.
In my example, it's a channel conversation where I want to perform a standard reply to a channel post, rather than starting a new post.
Quite possibly the code path is the same though.

But also - I would argue that the presence in the SDK of a ReplyToActivityAsync method, which does not actually perform a reply, is a bug and not a missing feature!

looks like this feature request? https://techcommunity.microsoft.com/t5/teams-developer/how-to-send-a-message-to-a-thread-reply-using-botbuilder-4-0-sdk/m-p/3716974

I think this bug / missing feature is very annoying, especially since we make heavy use of group chats.

In hope this saves someone some time, we got replies working like this:
connector.Conversations.SendToConversationAsync($"{groupChatId};messageid={conversationId}", (Activity) message);

Anxiously waiting to see something happen with this.
